Question

The temperature of a substance is a measure of the
1.
average kinetic energy of its particles
2.
average potential energy of its particles
3.
ionization energy of its particles
4.
activation energy of its particles

Answer 1

Answer:

1.  average kinetic energy of its particles

Explanation:

The temperature of a substance is a measure of the average kinetic energy of its particles.

The average kinetic energy of the particles of a substance is directly proportional to its temperature. This is one of the premise of the kinetic theory of gases.

• When thermal energy is supplied to a substance, the molecules gains kinetic energy.
• As the kinetic energy increases so also the temperature of the substance.
• So, we see that kinetic energy and temperature are connected through the thermal energy acquired by the substance.
