Thermal Energy and Kinetic Energy Quiz (OL)

What is thermal equilibrium?

• The state where all substances within a system have the same temperature.

• The process of heat moving from cooler to warmer substances.

• The point at which kinetic energy is at its maximum.

• The state where substances within a system have different temperatures.
