17-2 Heat Transfer

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 transfer of heat through direct contact between materials.

Front

Give an example of conduction.

Back

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

Front

Define convection.

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

Give an example of convection.

Back

An example of convection is warm air rising and cool air sinking, creating a breeze.

Front

Define radiation.

Back

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

Front

Give an example of radiation.

Back

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

Front

What instrument is used to measure temperature?

Back

A thermometer is used to measure temperature.
