Types of Heat Transfer

Front

What is heat transfer?

Back

The movement of thermal energy from one object or substance to another due to a temperature difference.

Front

How does heat move?

Back

From a warmer object to a cooler object.

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) due to differences in density.

Front

What is radiation?

Back

The transfer of energy through electromagnetic waves, which can occur in a vacuum.

Front

What is an example of conduction?

Back

Touching a hot stove and getting burned.

Front

What is an example of convection?

Back

Boiling water where the hot water rises and cooler water sinks.

Front

What is an example of radiation?

Back

The Sun's heat reaching the Earth.

Front

What happens to heat energy when it is transferred?

Back

It moves from areas of higher temperature to areas of lower temperature.

Front

What is thermal equilibrium?

Back

A state where two objects in contact reach the same temperature and no heat flows between them.
