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

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

Define radiation.

Back

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

Front

How does the sun transfer heat to the Earth?

Back

The sun transfers heat to the Earth through radiation.

Front

What happens to land compared to water when heated?

Back

Land heats up and cools down faster than water.

Front

What type of heat transfer occurs when you walk on warm sand?

Back

Walking on warm sand demonstrates conduction.

Front

What type of heat transfer occurs when using an iron on clothes?

Back

Using an iron on clothes transfers heat through conduction.

Front

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks in a room.
