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 temperature.

Front

Give an example of conduction in everyday life.

Back

An example of conduction is when marshmallows melt in hot chocolate due to direct contact with the hot liquid.

Front

Give an example of convection in everyday life.

Back

An example of convection is a fan cooling down a room by circulating air.

Front
