Thermal Energy Review

Front

What is the transfer of heat by currents through liquids or gases called?

Back

Convection

Front

What do we call the condition where two substances in physical contact exchange no heat energy?

Back

Thermal Equilibrium

Front

What happens when two objects with different temperatures in thermal contact reach thermal equilibrium?

Back

Both objects reach the same final temperature.

Front

In which direction does heat always travel?

Back

From hot to cold objects.

Front

What is the definition of conduction?

Back

When heat transfers from objects that are touching.

Front

What is thermal energy?

Back

The total kinetic energy of particles in a substance.

Front

What is radiation in terms of heat transfer?

Back

The transfer of heat through electromagnetic waves.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through fluid movement.

Front

What is an example of convection?

Back

Boiling water where hot water rises and cooler water sinks.

Front

What is thermal equilibrium?

Back

A state where two objects in contact have the same temperature and no heat flows between them.
