Conduction, Convection, Radiation

Front

What is conduction?

Back

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

Front

Example of conduction in daily life?

Back

Ironing a shirt is an example of conduction.

Front

What is convection?

Back

Convection is the transfer of heat through a fluid (liquid or gas) where hot fluid rises and cold fluid sinks.

Front

Example of convection?

Back

Boiling water is an example of convection.

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves, such as sunlight.

Front

Example of radiation?

Front

What happens to air when it is heated?

Back

Hot air expands, becomes less dense, and rises.

Front

What happens to cold air?

Back

Cold air is denser and sinks.

Front

What is the relationship between density and temperature in fluids?

Back

As temperature increases, density decreases; as temperature decreases, density increases.

What is an example of heat transfer in a snowball in your hand?

Back

The heat from your hand melts the snowball through conduction.
