Question

Give reasons for the following observation:
The smell of hot sizzling food reaches you several meters away,but to get the smell from cold food you have to go close

Answer 1

it is so because particles of hot food get diffused easily because it has high kinetic energy

but cold Food didn't had high kinetic energy so we need to go close

Answer 2

Particles in the air, if fueled with higher temperatures, acquire high kinetic energy which aids them to move fast over a stretch. Hence the smell of hot sizzling food reaches a person even at a distance of several meters.
