Front

What is the flow of energy from warmer places to cooler places due to a difference in temperature?

Back

Heat.

Front

What happens when heat flows from a higher temperature object to a lower temperature object until they reach equal temperature?

Back

Thermal equilibrium.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is thermal radiation?

Back

Thermal radiation is the transfer of heat in the form of electromagnetic waves.
