Thermal Energy Test

Front

What happens to the atoms of a substance when thermal energy is removed?

Back

The atoms vibrate slower.

Front

Why do atoms have kinetic energy?

Back

Because they are always vibrating.

Front

What is the primary factor that determines the direction of thermal energy transfer?

Back

Temperature difference.

Front

True or False: Thermal energy transfers well with insulators.

Back

False.

Front

What happens to an object as its thermal energy increases?

Back

It heats up.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance.

Front

What is an insulator?

Back

An insulator is a material that does not conduct thermal energy well.

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 and gases).

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves.
