Thermal Energy

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

NGSS.MS-PS3-4

An increase in the volume of a material due to a temperature increase in the material.

• Thermal contraction

• Thermal expansion

• Thermal heat

Thermal expansion occurs when particles of matter move farther apart as temperature increase.

• True

• False

The amount of heat needed to raise the temperature of one gram of a material by one degree Celsius is called

• Specific Temperature.

• Specific Heat

• Absolute Heat

The lower a material's specific heat, the more its temperature rises when a given amount of energy is absorbed by a given mass.

• True

• False
