What is heat transfer?

Back

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

Front

What are the three main methods of heat transfer?

Back

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

Front

Define conduction.

Back

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

Front

Define convection.

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.

Back

Radiation is the transfer of heat energy through electromagnetic waves without the need for a medium.

Front

Example of conduction in everyday life?

Back

Touching a hot stove and feeling the heat transfer to your hand.

Front

Example of convection in everyday life?

Back

Warm air rising from a heater and circulating in a room.

Front

Example of radiation in everyday life?

Back

Feeling the warmth of the sun on your skin.

Front

What happens to warm air in a closed room?

Back

How does a campfire transfer heat?

Back
