Answer
Both liquid water and ice have fixed volumes. Liquid water and ice contain water molecules surrounding one another, and both states are not compressible.
A difference between the two states is that liquid water does not have a definite shape whereas ice does have a definite shape. In liquid water, the water molecules can move quite freely, sliding over one another; with ice, the water molecules are fixed in space, surrounded by the same neighbors all the time.
