PROPERTIES OF WATER. *Water is a Polar molecule. •Intermolecular forces (forces between molecules) are Hydrogen Bonds. •Hydrogen Bonds are relatively strong form of intermolecular force. •Water is the only substance found commonly in all 3 states (solid, liquid and gas). •Relatively high melting point & boiling point. •Water expands on freezing. •Ice is less dense than water and floats on water. •High heat capacity.
