Thermal Energy Test Review

Front

What is thermal energy?

Back

The total kinetic energy of the particles in a substance.

Front

What is the Kelvin scale?

Back

A temperature scale used to measure absolute zero.

Front

What does equilibrium mean in terms of temperature?

Back

When the temperature is balanced in a system.

Front

What happens to heat when a hot object is placed in contact with a cold object?

Back

Heat moves from the hot object to the cold object.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves, without the need for a medium.

Front

What is absolute zero?

Back

The theoretical temperature at which all molecular motion stops, equivalent to 0 Kelvin.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the average kinetic energy of particles increases.

Front

What is a substance with high thermal energy?

Back

A substance that has a high temperature and therefore a high amount of kinetic energy.
