What is an insulator?

Back

An insulator is a material that does not conduct heat well. Examples include rubber, plastic, and glass.

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

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

Front

What happens to warm air or water when heated?

Back

Warm air or water rises because it is less dense than cool air or water.

Front

What is the definition of heat?

Back

Heat is the energy that is transferred from a warmer object to a cooler object.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of hot soup.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room.

Front

What is an example of radiation?

Back

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