Thermal Expansion and Contraction
Thermal Expansion is the increase in volume of a material due to a temperature increase.Thermal Expansion occurs because particles of matter tend to move farther apart as temperature increases. Contraction is when temperature decreases the space in between particles gets smaller or the particles move closer and volume decreases
