Heat and Temperature

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another.

Front

What are the three types of heat transfer?

Back

The three types of heat transfer are conduction, convection, and radiation.

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) 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.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, preventing heat transfer.

Front

Why does warm air rise?

Back

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

Front

What happens when two objects at different temperatures come into contact?

Back

Heat will transfer from the hotter object to the cooler object until they reach the same temperature.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat because they are at the same temperature.

How does a thermos keep drinks hot or cold?

Back

A thermos uses insulation to reduce heat transfer by conduction, convection, and radiation.
