Ans: At higher temperatures the particles of gas moves faster as the kinetic energy increases with increase in temperature . So the smell (vapour particles) of hot cooked food reach several meters within seconds.
Why does the smell of hot cooked food reaches you several Metres away within 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.
How does the smell of food being cooked spread so fast?
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 cooked food reach to us?
In cooked food, the particles of matter absorb heat and turn into gaseous state and mix with atmospheric air. So the smell of food reaches our nostrils without our entering the kitchen through air.
Why does hot sizzling food reaches smell?
At lower temperatures, particles in cold food have low kinetic energy. At higher temperatures, particles have high kinetic energy and move faster hence, due to this smell of hot sizzling food reaches you several meters away, but to get the smell from cold food you have to go close.
Why can’t we smell cold food?
Due to the leading factors of kinetic energy and temperature the smell of hot sizzling food reaches you several metres away, but to get the smell from cold food you have to go close.
How does this smell reach us?
There is a phenomenon called Diffusion. In diffusion, molecules of solid, liquid or gas spread from the region of their higher concentration to the region of their lower concentration. … By diffusion, the smell spreads to the whole room and thereby whole house, so anyone standing at a distance, Can smell it. THANKS!!
Is smell of food a matter?
Matter is made up of very small tiny particles which move continuously. … Smell of food — is not considered as matter as it does not satisfy the above said properties.It is just the smell / sensation that we feel and sense.
