What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases) caused by differences in temperature.

What happens to molecules when they are heated?

Back

When molecules are heated, they gain energy and move faster, which can increase the temperature of the substance.
