Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which determines its temperature.

Front

What are the three methods of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

Define conduction.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

Give an example of conduction.

Back

An ice cube melting in a person's hand.

Front

Define convection.

Back

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

Front

Give an example of convection.

Back

A furnace heating the air in a room.

Front

Define radiation.

Back

Radiation is the transfer of heat through electromagnetic waves without the need for a medium.

Front

Give an example of radiation.

Back

The sun heating water in a swimming pool.

Front

What happens to particles in a substance when it is heated?

Back

The particles gain kinetic energy and move faster.

Front

What is the role of thermal energy in cooking?

Back

Thermal energy transfers heat to food, causing it to cook.
