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, where heat moves from the hotter object to the cooler one.

Give an example of conduction.

Back

An example of conduction is when a metal spoon gets hot after being placed in a pot of hot soup.

Define convection.

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself.

Give an example of convection.

Back

An example of convection is when warm air rises and cool air sinks, creating a circular motion in a room.

Front

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, without the need for a medium.

Give an example of radiation.

Back

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

Front

What happens to the density of a fluid when it is heated?

Back

When a fluid is heated, its density decreases, causing it to rise.

What is the role of temperature in heat transfer?

Back

Temperature is the measure of thermal energy; heat transfer occurs from areas of higher temperature to areas of lower temperature.
