What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself.

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) due to differences in temperature and density.
