Thermal energy and Heat

Heat flows spontaneously from hot objects to

• hot objects.

• cold objects.

Temperature is related to the average kinetic energy of the particles in an object due to their random motions through space.

• True

• False

Temperature is a measure of how

• the particles are stationary.

• energy remains the same.

• hot or cold an object is compared to a reference point.

In what direction does heat flow?

• cold to hot

• cold to cold

• hot to hot

• hot to cold

This type of energy depends on mass, temperature and the phase of an object.

• nuclear

• chemical

• thermal

• electrical

Any material that conducts thermal energy good.

• thermal conductor

• thermal insulator

Any material that conducts thermal energy poorly.

• thermal conductor

• thermal insulator
