Problem
When ice melts to form liquid water at 0∘C , there is a contraction in volume. This is due to :
(1) the molecules contracting in size
(2) a partial disruption of the hydrogen bonded network of ice on melting
(3) the absorption of heat during the melting process
(4) the dissolving of air into the water during the melting process
