Heat Transfer

Front

What is heat transfer?

Back

The process of thermal energy moving from one object or substance to another.

Front

What are the three main types of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

Define conduction.

Back

The transfer of heat through direct contact between materials.

Front

Define convection.

Back

The transfer of heat by the movement of fluids (liquids or gases).

Front

Define radiation.

Back

The transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

What is an example of conduction?

Back

Touching a hot stove and getting burned.

Front

What is an example of convection?

Back

Boiling water where the hot water rises and cooler water sinks.

Front

What is an example of radiation?

Back

Feeling the warmth of the sun on your skin.

Front

How does heat transfer occur in a vacuum?

Back

Only through radiation, as there are no particles to conduct or convect heat.

Front

What happens to air when it is heated?

Back

It becomes less dense and rises, creating convection currents.
