When ice melts into water is a physical change. Take a piece of ince in small flash, cork is and weight it. (W(ice) gm). Heat the falsk gentyl and ice (Solid) slowly melts into water (liquid). Weight the flash again (water gm). It is found there is no change in the weight i.e..
`W_(("ice")=W_(("water"))`
`1ce underline ("Heat" (Delta))` water
This shows law of conservation of mass holds true for physical change.
