Heat Transfer Practice

Front

What is conduction?

Back

Conduction is the transfer of heat from one object to another through direct contact.

Front

What conditions are necessary for heat conduction to occur?

Back

Two objects at different temperatures must be touching one another.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or infrared radiation.

Front

Give an example of conduction.

Back

An ice cube melting in a person’s hand.

Front

Give an example of convection.

Back

A furnace heating the air in a room.

Front

Give an example of radiation.

Back

The sun heating water in a swimming pool.

Front

What is the role of temperature in heat transfer?

Back

Heat transfer occurs from areas of higher temperature to areas of lower temperature.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state reached when two objects in contact have the same temperature and no heat flows between them.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, such as rubber or wood.
