Thermal Energy Flashcard

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in an object, which is related to its temperature.

Front

What is temperature a measure of?

Back

Temperature is a way we measure energy.

Front

Why do icebergs have more thermal energy than boiling water?

Back

Icebergs contain many more molecules than pots of water.

Front

What type of heat transfer occurs when warm air rises and cool air sinks?

Back

Convection.

Front

What is a unit of temperature?

Back

Celsius.

Front

What happens to molecules as temperature increases?

Back

Molecules move faster.

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 and gases).

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves.

Front

What is the difference between thermal energy and temperature?

Back

Thermal energy is the total energy of all particles in an object, while temperature measures the average energy of those particles.
