Thermal Energy - Heat Transfer

Front

What are the three ways that heat is transferred in thermal energy?

Back

Conduction, convection, and radiation.

Front

What is a thermal insulator?

Back

A material that does not allow heat to easily pass through it or escape.

Front

How does heat transfer by radiation occur?

Back

Heat transfer by radiation happens when there is space that heat travels through in waves outwardly.

Front

What is an example of heat transfer by radiation?

Back

Warming your hands near a campfire.

Front

What type of heat transfer occurs when feet get warm while in hot sand on the beach?

Back

Conduction.

Front

Define conduction in the context of heat transfer.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

Define convection in the context of heat transfer.

Back

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

Front

Define radiation in the context of heat transfer.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

What is an example of convection?

Back

Boiling water where hot water rises and cold water sinks.

Front

What happens to the temperature of a thermal conductor when it is heated?

Back

The temperature of a thermal conductor increases as it allows heat to pass through easily.
