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 methods of heat transfer?

Back

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 energy through electromagnetic waves without the need for a medium.

Front

Why can a wooden spoon be used to stir hot soup?

Back

Wood is a poor conductor of heat, which means it does not transfer heat to the spoon, keeping it safe to touch.

Front

In which direction does heat travel?

Back

Heat travels from an area of high temperature to an area of low temperature.

Front

What is an example of conduction?

Back

Touching a hot handle and getting burned is an example of conduction.

Front

What is an example of convection?

Back

Boiling water is an example of convection, as the hot water rises and cooler water sinks.

Front

What is an example of radiation?

Back

Feeling warmth from a campfire is an example of radiation.
