Thermal Energy Transfer in Systems

Front

What is conduction?

Back

The transfer of energy through molecules in direct contact.

Front

What is convection?

Back

The flow of energy that occurs when a warm liquid or gas rises.

Front

What is radiation?

Back

The transfer of energy by electromagnetic waves.

Front

Why do icebergs contain more thermal energy than a pot of boiling water?

Back

Icebergs contain many more molecules than pots of water.

Front

What is thermal energy?

Back

The total kinetic energy of all the particles in a substance.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred due to temperature difference, while temperature is a measure of the average kinetic energy of particles.

Front

What is an example of conduction?

Back

Touching a hot stove.

Front

What is an example of convection?

Back

Warm air rising and cool air sinking in a room.

Front

What is an example of radiation?

Back

The Sun heating the Earth.

Front

What happens to thermal energy when ice melts?

Back

Thermal energy is absorbed, causing the ice to change from solid to liquid.
