Because liquids take up more room than solids. I'm definitely not an expert on this, but I do remember some A-level chemistry (or maybe it was GCSE?). The molecules in a solid don't move about. The molecules in a liquid do move and so are spread out more. So, even though you aren't adding more water, the volume of water is increasing because the molecules are moving further apart. Does that make sense?
