It is less dense when frozen than when it's a liquid.

Water freezes at 0°C, therefore the water molecules form a lattice crystalline structure maintained by hydrogen bonding. This Ice formed is less dense than water because the orientation of hydrogen bonds causes molecules of the ice to push farther apart hence lowering its density.

It takes a lot of energy to raise the temperature of water.

Specific heat capacity is the energy is takes to raise 1 mole of a substance to °C. For water, its specific heat capacity = 4.18 kJ/kg°C

Water molecules sticks to each other.

Forces of cohesion is the property of water molecules to stick to each other. Also, Hydrogen bonds are formed between adjacent water molecules because of the positive charged hydrogen end of one water molecule attracts the negative charged oxygen end of another water molecule.

It is a good solvent because both polar and nonpolar molecules dissolve in it.

Water is a univeral solvent because it dissolves a lot of solute unlike any other solvent. Water does not dissolve non-polar molecules because no hydrogen bond can be formed between them.
