Question

The smell of hot sizzling food reaches you several meters away but to get the smell from cold food you have to go close why???

Answer 1

It is bcoz of diffusion.As the temperature is more particles diffuse at a higher rate and we are able to smell it even far away,whereas in a cold food temperature is low so particles diffuse at a very slow rate so we have to go near to smell it. Hope it help!

Answer 2

This is because the kinetic energy rises with temperature.

So, when you have hot sizzling food, the aroma of the food reaches our nose easily and hence we get the smell of hot sizzling food.

But, in case of cold food we have to go close because the temperature is low and hence the kinetic energy is low. We have to go close to get the smell.

This is the reason why we get the smell of hot sizzling food from several meters away.

Hope this helps you.
