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.
