Question

the smell of hot sizzling food reaches you several metres away but to get smell from cold food you have to go close

Answer 1

Answer:

because in the cold food the molecules move slowly but in the hot sizzling food the molecules are loose and can travel far away

Answer 2

At higher temperatures, the kinetic energy of the particles is high so they vibrate more as well as faster. So they reach farther distance when the food is hot and diffuse into the air to give the sensation of smell. When the food is cold, particles do not have enough kinetic energy so we have to go close to get the smell.
