The smell of food being cooked spreads very fast because of the kinetic energy produced. whenever there is an increase in temperature the kinetic energy also increases causing the particles of matter to move fastly by the process of diffusion. it is the process in which particle mix and spread and then reach to us.
How does smell of cooked food spread so fast?
When we increase temperature, the particles move with more speed and gain kinetic energy. Hot food has a very high temperature. Thus it spreads to a very large distance. So we can say that we smell hot food from a distance because of diffusion.
How does food smell when cooked?
The smell of food cooked in the kitchen reaches us even from a considerable distance because the tiny particles of the vapour of food mix with the air and move continuously in all directions by the process of diffusion.
Why the smell of hot cooked food reaches us in seconds?
The smell of hot cooked food reaches us in seconds. This is due to high speed of particles (kinetic energy) of gases and large space between them shows the property of diffusing very fast into other gases. In the gaseous state, the particles move about randomly at high speed.
Can you smell food cooking?
When we cook food in the kitchen, that’s the region of higher concentration of the smell. By diffusion, the smell spreads to the whole room and thereby whole house, so anyone standing at a distance, Can smell it. THANKS!!
How does the smell of food being cooked spread so fast Class 6?
Answer : The particles of the aroma of hot cooked food mix with the particles of air spread from the kitchen, reach us and even farther away, in seconds. Due to high speed of particles and large space between them, gases show the property of diffusing very fast into other gases.
How does the smell of cooked food reach our nostrils even without entering the kitchen?
Answer: The particles of aroma of food mix with the particles of air through diffusion and reach our nostrils. Thus, we get the aroma of the food without entering in kitchen.
Why can I smell cooking?
An olfactory hallucination (phantosmia) makes you detect smells that aren’t really there in your environment. The odors you notice in phantosmia are different from person to person and may be foul or pleasant. You may notice the smells in one or both nostrils.
Why does it smell so good in the kitchen?
Heat, the aroma enhancer
In simple terms, we can say that in many dishes, heat ensures that the amino acids react with some types of sugar to form dicarbonyl which, in their turn, react with other amino acids to extend the reaction. This is how pleasant smells and flavours are amplified.
How does the smell of food being cooked in the kitchen reaches us even from considerable distance?

How does the smell of food being cooked in the kitchen reaches us even from a considerable distance class 9th?
Answer: The smell of food cooked in the kitchen reaches us even from a considerable distance because the tiny particles of the vapour of food mix with the air and move continuously in all directions. This process is called diffusion.
Why can we smell hot food easily Class 9?
We smell hot food from distance because of diffusion process. Diffusion is spreading out and intermixing of particles From one substance into another substances due to movement of particles. Particles move from high concentration region to low concentration region till uniform distribution is attained.
Why do I hate the smell of food cooking?
Hyperosmia is an overwhelming sensitivity to smells. There are many reasons behind this change in smell. Some include genetics, hormone changes, and migraines. If you have hyperosmia, your taste may also be affected.
How do we smell food?
These food odors or odorants are detected by receptor proteins on hair-like cilia at the tips of the sensory cells in your nose, which in turn send neural messages to the brain – these two messages are what we would perceive as a flavor or taste.
How does smell spread?
Smells travel through the air by a process called diffusion; air particles, and the odour particles within the air, move freely in all directions. They are constantly moving and eventually they spread out through the air around them.
When your mother cooks food you can smell the food across the house why Class 5?
When my mother cooks food , the aroma spreads across the house and can be smelled . This is because the gas molecules are in random motion and move in every space available to them . Since , they have a lot of kinetic motion within them they spread very fast across the whole house .
Why does smell of food diffuse from a bag to your nose?
Smells travel in the air by diffusion. Because molecules are always moving, some molecules leave the bread as it is baking. They are vented with the excess heat from the oven. These tiny molecules of bread travel through the air throughout the house to our noses.
How does the smell of food reach your nose?
❖ When we eat food, the food odors (small molecules) reach our nose e.g. by breathing in through the nose. But also while chewing, the food molecules pass through the air to the back of our mouth, on its way to the nose. This is called “retro-nasal smell”.
How do smells reach your nose?
Smells reach the olfactory sensory neurons through two pathways. The first pathway is through your nostrils. The second pathway is through a channel that connects the roof of the throat to the nose. Chewing food releases aromas that access the olfactory sensory neurons through the second channel.
How does the aroma of food reach her nose?
There are two routes by which odours reach the nasal cavity, where they are detected. In the orthonasal route, odours are inhaled up the nose (like the smell of freshly baked bread coming from the oven), whilst in the retronasal route, odours are released as we chew and travel up the back of the throat.
What do you smell before a stroke?
There is a common myth that during a stroke, the victim will perceive the smell of burning toast. The medical term for this is phantosmia; an olfactory hallucination. In other words, a phantom smell, or a smell that isn’t really there.
Why do I keep smelling poop in my nose?
If you have, you may have experienced phantosmia—the medical name for a smell hallucination. Phantosmia odors are often foul; some people smell feces or sewage, others describe smelling smoke or chemicals. These episodes can be sparked by a loud noise or change in the flow of air entering your nostrils.
What is Osmophobia?
Osmophobia, defined as a fear, aversion, or psychological hypersensitivity to odors, is a very rare isolated phobia. It is common among primary headache patients, with prevalence of migraine.

Which scientific phenomenon is involved when fragrance spreads in the house at the time of cooking of food in the kitchen?
Expert-verified answer
(a) Fragrance spreads in the house at the time of cooking of food in the kitchen ? The phenomena is known as diffusion. Diffusion is the process where molecules tend to spread out to occupy space that is available.
Why do we get the smell of hot food from the kitchen outside the house a Evaporation B Boiling C diffusion D Sublimation?
The kinetic energy of particle is more in hot food so their diffusion rate is also high that’s why the smell of hot food reaches us several metres away…. Usually,when the food is cooked at that time evaporation is occur and food smell is also comes out through evaporation.
How do we detect smell of hot spicy food from a distance class 10?
How do we detect smell of hot spicy food from a distance? We have olfactory receptors in our nose which detect the smell of hot spicy food. This information is transmitted by nerve impulse to olfactory lobes of forebrain which interpret the information.
Why is the odor of something baking more intense than the odor of cold items like ice cream?
why is the odor of just baked bread more intense than the odor of cold foods such as ice cream? heat converts many substances into their volatile form. because only volatile molecules in the form of gas carry odor, it is easier to smell hot foods than cold ones.
When you come home from school and open the door you can smell food being cooked?
Answer. Explanation: the kinetic energy of hot vapours is high so we find that we can smell tea being prepared at home.
Why do we get the smell of hot food faster than cold food?
Hot food increases the temperature of the air around it and hot air spreads faster and spreads more as compared to cold air, so the smell of hot food comes faster than cold food.
Why diffusion becomes faster on heating?
Upon increasing temperature the kinetic energy of the particles increases, as a result the particles start moving with high speed and intermix more rapidly with each other and so the rate of diffusion increases with heating.
Do smells rise or sink?
Whether odor smells will travel upward or downward then is not determined by the mass of their constituting particles (related to their vapor densities) but rather by their initial concentrations (or rather their gradients).
Is Indian food smelly?
Indian food, of course, uses many aromatic spices – Jaffrey suggests that some, like methi and hing, are particularly responsible for lingering smells. The tarka process, which is central to so much Indian cooking, specifically involves frying spices to release aromas.
Why do people like the smell of bacon?
1 – The Maillard reaction
Discovered by French chemist, Louis-Camille Maillard in 1912, the reaction is triggered by heating meat like bacon, producing tempting smells. As the Telegraph reports ‘The majority of these ‘aroma’ compounds are hydrocarbons (35%) and aldehydes (31%), both of which give off alluring aromas. ‘
Why do I gag at the smell of food?
It’s normal to not like certain foods. Food aversion causes you to reject a specific food because your brain tells your body that it’s inedible. It also causes your body to react negatively by feeling nauseous or gagging, at the sight, scent or taste of the food.
Is taste 70% smell?
Abstract. It is frequently asserted that somewhere between 75 and 95 % of what we commonly think of as taste actually comes from the sense of smell.
Which process brings you the smell of food which is cooking on the stove when you enter the kitchen?
A Maillard reaction is a browning reaction that gives foods an aromatic and mouth-watering aroma. Usually triggered by heat, this occurs when an amino acid and certain types of sugars break down and then recombine into hundreds of different types of compounds.
How does taste and smell work?
The chemical senses include taste and smell. The perception of a smell occurs when substances in the air pass through the nose and stimulate the olfactory (smell) nerve. The experience of taste, or gustation, occurs when the taste buds in your mouth respond to substances dissolved in saliva.
What does death smell like?
A decomposing body will typically have a smell of rotting meat with fruity undertones.
What does a period smell like?
“Healthy” periods can have a slight smell of blood. They may even have a slight metallic smell from iron and bacteria. Generally speaking, period odors aren’t noticeable to others. Good hygiene practices can also combat normal period odors and make you more comfortable during menstruation.
How does smell travel so fast?
The time it takes to smell a chemical in the air is the time the chemical takes to travel in air to our nose, and for the nerve impulse to travel to the brain (milliseconds), so smells are almost instantaneous.

Answer: The particles of aroma of food mix with the particles of air through diffusion and reach our nostrils. Thus, we get the aroma of the food without entering in kitchen.
Does pinching your nose stop you tasting?
The latter occurs because the back of your throat connects your nose and mouth. The only catch is that air needs to be flowing in or out of your nose for the odor molecules to get into the nose—either through the front or the back. This explains why pinching your nose prevents you from smelling food.
Do brains smell?
In experiments in mice, NYU Grossman School of Medicine researchers have for the first time created an electrical signature that is perceived as an odor in the brain’s smell-processing center, the olfactory bulb, even though the odor does not exist.
Why do smells trigger emotions?
Scents bypass the thalamus and go straight to the brain’s smell center, known as the olfactory bulb. The olfactory bulb is directly connected to the amygdala and hippocampus, which might explain why the smell of something can so immediately trigger a detailed memory or even intense emotion.
Why can you smell food cooking when you are in the next room?
The smell of food cooked in the kitchen reaches us even from a considerable distance because the tiny particles of the vapour of food mix with the air and move continuously in all directions by the process of diffusion.
How does temperature affect the aroma of food?
A new study published in the journal Chemosensory Perception found that food temperatures would affect how intense a flavor was. For instance, bitterness was more intense in cold solutions, while sour flavors were more intense in warm solutions.
