The boiling point water is exceptionally high because
1 There is covalent bond between \(\mathrm{\mathrm{H}}\) and \(\mathrm{\mathrm{O}}\)
2 Water molecule is linear
3 Water molecules associate due to hydrogen bonding
4 Water molecular is not linear
Explanation:
Water molecules associate due to intermolecular hydrogen bonding.

Water contracts on heating
1 To \(\mathrm{100^{\circ} \mathrm{C}}\)
2 From \(\mathrm{0^{\circ} \mathrm{C}}\) to \(\mathrm{4^{\circ} \mathrm{C}}\)
3 To \(\mathrm{273 \mathrm{~K}}\)
4 From \(\mathrm{10^{\circ} \mathrm{C}}\) to \(\mathrm{20^{\circ} \mathrm{C}}\)
Explanation:
When water is heated from \(\mathrm{0^{\circ} \mathrm{C}}\) to \(\mathrm{4^{\circ} \mathrm{C}}\), its density increases and volume decreases\(\rm{\left(d=\dfrac{m}{V}\right)}\)

The maximum possible number of hydrogen bonds a water molecule can form in ice is
1 1
2 2
3 3
4 4
Explanation:
In ice, each \(\mathrm{\mathrm{H}_{2} \mathrm{O}}\) molecule is surrounded by four other water molecules, bonded through H-bonds.
