Heat Transfer Flashcard

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What are the three main types of heat transfer?

Back

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

Front

Define conduction.

Back

Conduction is the direct transfer of heat between objects that are in contact with each other.

Front

Give an example of conduction.

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.

Front

Define convection.

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

Give an example of convection.

Back

An example of convection is boiling water, where hot water rises and cooler water sinks.

Front

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or infrared radiation.

Front

Give an example of radiation.

Back

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

Front

What is the role of the sun in heat transfer?

Back

The sun warms the Earth primarily through radiation.

Front

What happens to heat during conduction?

Back

During conduction, heat moves from the hotter object to the cooler object until they reach the same temperature.
