Thermal Energy Transfer Review

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 or gases) where warm air rises and cool air sinks.

Front

What is radiation?

Back

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

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through it easily, such as metals.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat to pass through it easily, such as rubber or wood.

Front

Which of the following is NOT a type of heat transfer: Conduction, Convection, Radiation, or Transformation?

Back

Transformation is NOT a type of heat transfer.

Front

What happens to warm air in convection?

Back

Warm air rises because it is less dense than cool air.

Front

What happens to cool air in convection?

Back

Cool air falls because it is denser than warm air.

Front

Give an example of conduction in everyday life.

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

Give an example of convection in everyday life.

Back

An example of convection is the way warm air circulates in a room when a heater is on.
