Question

Give reason for the following:
The smell of hat sizzling food reaches you several metres away ..but..to get the smell from cold food you have to go to close

Answer 1

EXPLANATION

hot sizzling food has more heat,more kinetic energy,hence more motion in particles of food-in simple words evaporation of food particles takes faster and at a high rate......which allows smell of hot sizzling food reaches you several metres away while on the other hand cold food has less heat and less kinetic energy as a result rate of evaporation decreases and have to get closer to get the smell of cold food

Answer 2

When food is hot, diffusion is more. But in cold food diffusion is slow. Hence to get the smell from cold food we have to go close.
