To demonstrate that matter is conserved during a physical change, the following procedure can be used:
Find the mass of a piece of ice. Let the ice melt. Find the mass of the liquid water.
This procedure involves measuring the mass of the ice before it undergoes a physical change (melting) and then measuring the mass of the resulting liquid water. If the mass before melting is equal to the mass after melting, it shows that matter is conserved during the physical change.
