What is Thermal Equilibrium?

Back

The condition where two substances in physical contact with each other exchange no heat energy and are said to be at the same temperature.

What is heat transfer?

Back

The movement of thermal energy from one object or substance to another.

Front

What are the three methods of heat transfer?

Back

Conduction, convection, and radiation.

Front

What happens during conduction?

Back

Heat is transferred through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

What direction does heat transfer occur?

Back

Heat always transfers from the hotter object to the colder object.

Front

What happens to the temperature of a substance when heat is added?

Back

The temperature of the substance generally increases.

Front

What happens to the temperature of a substance when heat is removed?

Back

The temperature of the substance generally decreases.

Front

What is an example of conduction?

Back

A metal spoon getting hot when placed in a hot soup.
