Question 5

when the molecules of gases are heated, the average kinetic energy of the molecules increases.

1)true

2)false

The given statement is true.

As the more amount of heat is supplied to the object, the particle experience more amount of movement due to increase in kinetic energy. Under normal condition, the gaseous particles remain at rest and lacks motion.

As the space between the particles is very more in case of gases, the movement in particles is very slow. When to such condition, temperature is increased by heating; it causes increase of kinetic energy which in turn paves way for more amount of kinetic energy in particles.
