Question

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

Answer 1

Answer:

hot particles travel through air faster than the cold particles of food. it is because the kinetic energy increases with the increase in temperature.

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.
