Properties of Water

Hydrogen bonds A hydrogen bond from when a hydrogen is bonded to an electronegative atom. That hydrogen will then form a bond with a lone pair of electrons on another molecule

The hydrogen bonds that form with water give it unique properties. These properties causes its – high boiling point – High surface tension Surface tension is the inward force, or pull, that tends to minimize the surface area of a liquid.

Other properties To heat water it takes 4.18 J/(g°C) this is known as the specific heat of water. It takes 2.26 kJ to convert 1 g of liquid water at 100 °C to 1 g of water vapor.

Freezing water Molecules are in constant motion. When water freezes it limits the motion of the molecules. When water freezes its structure becomes more ridged. The molecules space out because of the hydrogen bonds and it becomes less dense.
