What is the relationship between a substance’s thermal energy and its kinetic energy?(1 point)

Responses

A substance’s thermal energy is the same as its kinetic energy.
A substance’s thermal energy is the same as its kinetic energy.

As the substance’s thermal energy increases, the kinetic energy of its particles decreases, and vice versa.
As the substance’s thermal energy increases, the kinetic energy of its particles decreases, and vice versa.

As the substance’s thermal energy increases, the kinetic energy of its particles increases, and vice versa.
As the substance’s thermal energy increases, the kinetic energy of its particles increases, and vice versa.

There is no relationship between a substance’s thermal energy and kinetic energy.

1 answer

The correct response is:

As the substance’s thermal energy increases, the kinetic energy of its particles increases, and vice versa.

Thermal energy is the total kinetic energy of the particles in a substance, so an increase in thermal energy corresponds to an increase in the average kinetic energy of those particles.
