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

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 warm air rising above a heater, creating a circulation of air.

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.

Front

Give an example of radiation.

Back

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

What is the role of copper in cookware?

Back

Copper is used in cookware because it conducts heat efficiently, allowing for even cooking.

Front

How does heat transfer occur in the Earth's mantle?

Back

Heat transfer in the Earth's mantle occurs primarily through convection, as hot material rises and cooler material sinks.
