Thermal Energy Review

Front

What is thermal energy?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, which can occur in a vacuum.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, preventing thermal energy transfer.

Front

What is a conductor?

Back

A conductor is a material that allows heat to flow through it easily.

Front

How does thermal energy transfer in the ocean?

Back

Thermal energy in the ocean is primarily transferred through convection, causing ocean currents.

Front

What happens when two objects of different temperatures touch?

Back

Thermal energy is transferred from the hotter object to the cooler object through conduction.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot soup.

Front

What is an example of convection?

Back

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