Heat Transfer Review

Front

What is conduction?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves, such as sunlight.

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 happens to warm air in convection?

Back

Warm air expands, becomes less dense, and rises, while cold air becomes more dense and sinks.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon gets hot after being placed in a hot soup.

Front

What is an example of radiation?

Back

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

Front

What is an example of convection?

Back

An example of convection is warm air rising from a heater and cold air sinking.

Front

How does the Gulf Stream demonstrate convection?

Back

The Gulf Stream is a current that moves warm ocean water from the south to the north, demonstrating convection.

Front

What is the role of density in convection?

Back

Density differences in fluids cause warmer, less dense fluid to rise and cooler, denser fluid to sink.

Front

What is the primary method of heat transfer from a fire to a person sitting nearby?

Back

The primary method is radiation.
