Question

why hot sizzling food smells too much as the cold food?

Answer 1

The smell of hot sizzling food reaches you at a distance. It is because of evaporation of some of liquid from the food. The liquid from a hot sizzling food forms vapors due to high temperature. ... But in the case of cold food the rate of evaporation from the food is very low due to its low temperature.

Answer 2

When molecules of some volatile substances from hot sizzling food diffuse into air and reach the odur sensitive part of our nose we have the perception of smell.

At higher temperature of molecules diffuse into air at a faster rate and therefore travel long distances.

Hence the smell of hot sizzling food reaches as quickly even when we are several metres away.

While on the contrary , when the food is called the vapour diffuse is at a slower rate and therefore does not travel longer distances.

So, one has to come closer to have the perception of smell.
