Heat Transfer Taskcards

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between molecules, where faster-moving molecules collide with slower-moving ones, transferring energy.

Front

What are the three main ways heat can transfer?

Back

Conduction, Convection, Radiation.

Front

True or False: Heat always transfers from colder substances to hotter substances.

Back

FALSE. Heat transfers from hotter substances to colder substances.

Front

Give an example of conduction.

Back

Touching a hot surface.

Front

What temperature does a cup of ice water need to reach for thermal equilibrium with a room at 72° F?

Back

72° F.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer areas of a liquid or gas rise and cooler areas sink.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight warming your skin.

Front

How does heat transfer in a pot of boiling water?

Back

Heat transfers through convection as the hot water rises and cooler water sinks.

Front

What happens to the thermal energy of a substance when it is heated?

Back

The thermal energy increases, causing the molecules to move faster.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects reach the same temperature and no heat flows between them.
