Question

why it is that to smell cold food, we have to go close but smell of hot food reaches us several meters away​

Answer 1

Answer:

it is difficult to smell the cold food from a distance but easy to smell hot food several meters away because when the food is hot, the particles of aroma accelerates and travells faster and farther because it gets fused in air.

Answer 2

In hot food, the particles are at high temperature so quickly changes to vapour and hence the vapours have greater kinetic energy so travel faster and travel to far off distances.

Whereas in cold food, because of temperature being low, particles do not change to vapour state and hence cannot travel faster so the smell does not reaches to a person sitting far away.
