Energy Transfer

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

Provide an example of convection in everyday life.

Back

Baking food in the oven is a common example of convection.

Front

What is 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

Provide an example of conduction in everyday life.

Back

An ice cube melting in your hand is an example of conduction.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

Provide an example of radiation in everyday life.

Back

Microwave cooking food is an example of radiation.

Front

What type of heat transfer occurs when walking on warm sand?

Back

Walking on warm sand demonstrates conduction.

Front

What happens to a huge rock in the park during the day?

Back

A huge rock gets hot during the day because of radiation.

Front

What are the three main types of heat transfer?

Back

The three main types of heat transfer are conduction, convection, and radiation.

Front

How does convection differ from conduction?

Back

Convection involves the movement of fluids to transfer heat, while conduction requires direct contact between materials.
