Question Question 2
Give reasons for the following observation:
The smell of hot sizzling food reaches you several meters away, but to get the smell from cold food, you have to go close.
Particles of matter are continuously moving as they possess kinetic energy. An increase in temperature increases the kinetic energy of particles hence they start moving faster and can move several meters quickly. Therefore, the smell of hot sizzling food reaches a person even at a distance of several meters but to get the smell from cold food, we have to go close.
