Ice
and water both contains H2O molecules but in water H2O
molecules are more compactly arrange than in ice.
Ice
has a hexagonal cage like structure, inside it H2O
molecules are not closely packed.hence there is more vacant
space between the molecules of ice. As a result the volume
increases due to the vacant spaces. As a result density of ice
decrease.
Other
hand,On increasing temperature then kinetic energy of molecules increases as
result the interaction between the molecules decrease and as a result the the
molecules come closer to each other and the volume decreases, so the density
increases.
The density of water is maximum at 3.98 ℃ approximately 4 degree celsius.
