Answer:
1. average kinetic energy of its particles
Step-by-step 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.
