The Physical Setting

"Observe and describe heating and cooling events."

Heat moves in predictable ways, flowing from warmer objects to cooler ones, until both reach the same temperature.
Heat can be transferred through material by the collision of atoms (conduction) or across space (radiation). in a liquid or gas, currents will help the transfer of heat (convection).
During a phase change, heat energy is absorbed or released. Energy is absorbed when a solid changes to a liquid and when a liquid changes to a gas. Energy is released when a gas changes to a liquid and when a liquid changes to a solid.
Most substances expand when heated and contract when cooled. Water is an exception, expanding when changing to ice.
Temperature affects the soluabiltiy of some substances in water.
