Question

Which statement explains the kinetic theory of heat?

A. Objects whose particles are at the same temperature are in thermal equilibrium.


B. Heat is transferred as thermal energy by the interaction of moving particles.


C. Objects are made of tiny particles, and their motion depends on the temperature.


D. An object's thermal energy is caused by the movement of the tiny particles that it is made of.

Answer 1

A. Objects whose particles are at the same temperature are in thermal equilibrium.

Step-by-step explanation:

Kinetic theory of heat is the temperature of a body that is determined by the average kinetic energy of its particles. Objects whose particles experience the same temperature are in thermal equilibrium. Thermal equilibrium means the stability of temperature of an object or no change occur in the body's temperature and the temperature remains the same.
