Amplify Thermal Energy Review

Front

What is Equilibrium?

Back

A balanced state in which a system is stable, such as when two samples are at the same temperature.

Front

When does heat transfer occur between two objects that are touching?

Back

There is a difference in temperature between samples.

Front

How does kinetic energy transfer when two things are in contact?

Back

From fast-moving molecules to slower-moving molecules.

Front

Why does the tile floor feel cold to James after a hot shower?

Back

Heat from his feet is transferred to the tile floor.

Front

What happens to the temperature of a sample if its molecules speed up?

Back

The temperature of the sample increases.

Front

What is thermal energy?

Back

The total kinetic energy of all the particles in a substance.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat by the movement of fluids (liquids or gases).

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the average kinetic energy of the molecules increases.
