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.
How does the smell of food being 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.
How we get smell of cooking food from a distance?
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 the smell of cooking spread all over the house?
If someone is cooking in the kitchen, the smell travels around the house to other rooms. This is because of diffusion , the movement of particles from an area of high concentration to an area of low concentration. For diffusion to work, the particles must be able to move around.
When food cooks you can smell it because?
Diffusion . The molecules causing the scent will spread out through the air. If the air near the food can circulate towards you, then that air can carry the molecules that cause the scent. If the concentration of molecules is high enough when it reaches you, then you can smell the food.
When a bottle of perfume was opened in a room?
When a bottle of perfume is opened in a room, the particles of perfume, start diffusing into the air surrounding the bottle. These particles of perfume keep moving towards a region of lower concentration by virtue of their kinetic energy.
Why we smell the food being cooked by your mother?
When your mom cooks food the food is hot and when food is hot, the smell gets transported easily in air. As air is present all over your house, the smell spreads.
Why we can smell hot food from a distance class 9?
We smell hot food from distance because of diffusion process. … As rate of diffusion increases with increase in temperature. As hot food has more temperature , the particles gain Kinetic energy and move with greater speed. Hence it spreads a greater DISTANCE.
How does smell travel through air?
A smell is created when a substance releases molecules (particles) into the air. … 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.
Why does the smell of hot cooked food spread out easily?
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.
Can you smell the aroma of food being cooked in the kitchen even when you are in the living room or bedroom?
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!!
What is the best thing to absorb odors?
Baking soda is very effective at absorbing odors from the air as well as from surfaces. Put baking soda in your trash can to eliminate orders, and sprinkle it on any surface an odor emits. Leave it on for an hour, then sweep it off.
Why when a bottle of perfume is opened in a room we can smell it even from a considerable distance?
When we open a bottle of perfume in a room, we can smell it even from considerable distance. This is because, when the perfume is opened, that gas of the perfume moves from its areas of high concentration to its areas of low concentration. This process is called diffusion.
