Types of Heat Transfer

Front

What is convection?

Back

Convection is the type of heat transfer that occurs in fluids (liquids and gases) where warm air or liquid rises and cold air or liquid sinks.

Front

What is conduction?

Back

Conduction is the transfer of heat that occurs when objects are touching each other.

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves, such as light from the sun.

Front

What are the three types of heat transfer?

Back

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

Front

What happens to warm air in convection?

Back

Warm air expands, becomes less dense, and rises.

Front

What happens to cold air in convection?

Back

Cold air becomes more dense and sinks.

Front

In a lava lamp, what type of heat transfer is demonstrated?

Back

Convection is demonstrated in a lava lamp as the wax rises when heated and falls when cooled.

Front

What is true about two objects when heat is passed between them?

Back

They are at different temperatures.

Front

How does heat transfer occur in conduction?

Back

Heat transfers from one object to another through direct contact.

Front

Can heat transfer occur in a vacuum?

Back

Yes, heat transfer can occur through radiation in a vacuum.
