Thermal Energy

Front

What is thermal energy?

Back

The total kinetic and potential energy of all particles in an object.

Front

What direction does heat move?

Back

Heat moves from warmer to cooler areas.

Front

What is convection?

Back

A type of heat transfer that occurs through the movement of fluids (liquids or gases).

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves, such as sunlight.

Front

What is an example of convection?

Back

Water currents that flow from the equator to the poles, moving heat from warmer to colder areas.

Front

What happens to thermal energy when cooking a pizza in an oven?

Back

The oven transfers thermal energy to the pizza, but the oven itself does not lose energy.

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

How does temperature relate to thermal energy?

Back

Temperature is a measure of the average kinetic energy of particles in a substance.

Front

What is an insulator?

Back

A material that does not conduct heat well, reducing heat transfer.
