Thermal Energy & Heat Review

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total energy of all the particles in an object.

Front

What is heat transfer?

Back

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

Front

What are the three types of heat transfer?

Back

The three types of heat transfer are 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 in the form of electromagnetic waves, such as sunlight.

Front

What happens to heat when two objects at different temperatures touch?

Back

Heat will always transfer from the hottest object to the coolest object.

Front

Which material is a good conductor of thermal energy?

Back

Silver is a good conductor of thermal energy.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, such as wood or plastic.

Front

How does the sun warm the Earth?

Back

The sun warms the Earth through radiation, as sunlight travels through space and heats the surface.
