Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in a sample of matter.

Front

How is thermal energy transferred?

Back

Thermal energy is transferred from a hotter object to a cooler one.

Front

What is 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 is an example of conduction.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What happens to particles as they heat up?

Back

As particles heat up, they move faster.

Front

What happens to particles as they cool down?

Back

As particles cool down, they slow down.

Front

What is the relationship between temperature and thermal energy?

Back

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

Front

What is convection?

Back

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

Front

Give an example of convection.

Back

An example of convection is warm air rising and cool air sinking.
