1. Changes in the magnitude in water stores
What can cause diurnal (daily)changes between stores of water?

2. In order for water to change from a solid to liquid and finally to a gas, the water molecule must gain energy. The energy absorbed by water is used to break the hydrogen bonds between groups of molecules. When the bonds are broken between the molecules of ice, it melts and they can circulate as a fluid. The energy required to convert ice into water is called the latent heat of fusion. It takes about 80 calories of heat to convert one gram of ice into water.
