Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat from one object to another through direct contact.

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

What is radiation?

Back

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

How does a microwave heat food?

Back

A microwave heats food primarily through radiation.

Front

What happens to air when it is heated?

Back

When air is heated, it expands, becomes less dense, and rises.

Front

What is an example of conduction?

Back

Touching a hot piece of metal is an example of conduction.

Front

What is an example of convection?

Back

A large house being heated by a heater that warms the air as it circulates is an example of convection.

Front

What is an example of radiation?

Back

Getting sunburned is an example of radiation.

Front

What is the role of density in convection?

Back

In convection, warmer, less dense fluids rise while cooler, denser fluids sink.

Front

How does heat transfer in a solid object?

Back

In a solid object, heat transfers through conduction.
