Answer 2

Since heat increases the kinetic energy of molecules, the aroma of hot sizzling food is diffused in the air faster than that of a cold food. Increase in the temperature increases the rate of diffusion. Therefore.the smell of hot sizzling food reaches you several meters away but to get the smell from cold food you have to go close.
