heat transfer

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy 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

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 wind.

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 feeling the warmth of the sun on your skin.

Front

What causes convection currents in the Earth's mantle?

Back

Convection currents in the Earth's mantle are caused by the heat from the core, causing hot magma to rise and cooler magma to sink.

Front

How does convection affect weather patterns?

Back

Convection affects weather patterns by causing warm air to rise, leading to cloud formation and precipitation.
