Heat Transfer

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that do not need matter to move; they can travel through a vacuum.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat energy by electromagnetic waves through space.

Front

What is conduction?

Back

Conduction is the transfer of heat by 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.

Front

What is an example of conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection?

Back

An example of convection is warm air rising in a room, causing cooler air to move down.

Front

What is an example of radiation?

Back

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

Front

How does the Gulf Stream affect climate?

Back

The Gulf Stream brings warm ocean water from the south to the north, influencing the climate of coastal regions.

Front

What happens to warm air in a room?

Back

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

Front

What is the role of density in convection?

Back

In convection, warmer, less dense fluids rise while cooler, denser fluids sink, creating a circulation pattern.
