Heat Transfer Review

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one through physical touch.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm air or liquid rises, while cooler air or liquid sinks, creating a circulation pattern.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, allowing heat to be transferred through empty space.

Front

How many ways can heat move from one object to another?

Back

There are 3 ways: conduction, convection, and radiation.

What type of heat transfer occurs when warm air rises and cool air sinks?

Back

Convection.

Front

What type of heat transfer is responsible for the sun warming the Earth?

Back

Radiation.

Front

Give an example of conduction in everyday life.

Back

An example of conduction is when you touch a metal spoon that has been sitting in a hot pot of soup.

Front

Give an example of convection in everyday life.

Back

An example of convection is the way warm air rises from a heater and circulates around a room.

Front

Give an example of radiation in everyday life.

Back

An example of radiation is feeling the warmth of the sun on your skin.
