The way I do it is fairly obvious: when ice starts to melt, I create
a water object. The mass of the water increased by the amount that
the mass of the ice decreases. When the mass of the ice reaches 0,
it's destroyed.

The same trick can be applied to water-to-steam, water-to-ice and
steam-to-water.

If you don't want to go through the melting/freezing
boiling/condensing process, just destroy the ice object and replace
it with a water object, transferring any appropriate properties
between them that you need.
