Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object to another.

Front

What are the three methods of heat transfer?

Back

Conduction, convection, and radiation.

Front

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves.

Front

What is a conductor?

Back

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

Front

What is an insulator?

Back

An insulator is a material that does not allow heat to flow through it easily.
