Question

the smell of hot sizzling food reaches you several meter away,but to smell the cold food you have to go close.why​

Answer 1

Answer:

Explanation:

Because temperature is inversely proportional to KE that means when temperature increase KE of particles also increases . In case of hot food the particles have high temp that means high KE  which means particles have high speed. That’s why the smell of hot sizzling food reaches to us even when we r several metres away from it

Also gases show rapid diffusion n when the temp is also increase their speed of diffusion is very n very high and thus it takes fraction of seconds to get mix with other gas

While in cold food there is no temperature only coolness that means no increase in KE means less motion means no speed for particles to travel

The smell of hot sizzling food reaches u several metres away but to get the smell from cold food u need to go close

Answer 2

The smell of hot sizzling food reaches you several meter away,but to smell the cold food you have to go close thsi is because the hot food gains Kinetic energy due to rise in temperature and that is why it diffuses in the air and you could smell it for far.
