During cooling, the kinetic energy of the molecules falls. Why does this happen?
A.
The motion of the molecules increases.
B.
The motion of the molecules slows down.
C.
The Van der Waals forces between molecules decrease.
D.
The forces of attraction between the molecules are overcome.

Respuesta :

Answer:

The motion of the molecules slow down

Explanation:

In heating process, increase in the temperature increases the motion of the molecules and hence it gains the kinetic energy and moves.

While in the cooling process, decrease in temperature reduces the speed or motion of the molecules and that's why during cooling kinetic energy of the molecules falls down.

B. the motion of the molecules slows down

has to do with kinetic
