As the temperature of a sample of matter is increased, what happens to the average kinetic energy of the particles in the sample?
a. it decreases.
b. it increases.
c. it does not change.

B. It increases.

Explanation:

The kinetic energy is associated with the motion of the particles of a substance.

When the temperature increases, the movement will increase, which means that the velocity of the particles will increase.

According to the mathematical defenition of kinetic energy

The higher the velocity, the higher the kinetic energy.

If the matter is made by a monoatomic gas, the relation between the kinetic energy and temperature is even more evident:

R: gas constant

Na: Avogadro's number

T: temperature
