Zechariah Beard · Answer 1

Well, for example, when you have an ice cube (solid) and you melt it in a cup, the weight of the water after melting (liquid) will be the same as the solid.

Nothing can be created or destroyed without tampering.

The water only changed physically, turning from a liquid into a gas.

The matter did not change at all; it only evaporated and changed its form physically.

Kolby · Answer 2

Because if you let it melt and there is no evaporation there will be the same amount of water.
