Question :

the smell of hot sizzling food reaches you several metres away but to get the small smell from cold food you have to go closer why?

Answer :

The smell of hot sizzling food reaches us several metres away but to get the smell of cold food we have to go closer because kinetic energy is directly proportional to the temperature increased.

In hot food the temperature is high and that's why it's kinetic energy also become high. The smell mixes up in the air and with the air it reaches to us.

While in the cold food , the kinetic energy is very low.
