Front

What is conduction?

Back

Transfer of heat through direct contact between materials.

Front

What is convection?

Back

Transfer of heat through the movement of fluids or gases.

Front

What is thermal equilibrium?

Back

The state in which two objects in thermal contact no longer transfer heat to each other.

Front

What is specific heat?

Back

The amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.

Front

What is the difference between heat and temperature?

Back

Heat is the total energy of molecular motion in a substance, while temperature is the measure of the average energy of the particles.
