About this resource...

"Most matter expands when heated and contracts when cooled, a principle called thermal expansion. The average kinetic energy of the particles increases when matter is heated and this increase in motion increases the average distance between its atoms. It is important to note that water does not follow the rule of thermal expansion. Water expands when it freezes because the crystalline structure of ice takes up more space than liquid water."
