The procedure that could be used to demonstrate that matter is conserved during a physical change is:
Find the mass of a piece of ice. Let the ice melt. Find the mass of the liquid water.
This procedure shows that the mass of the ice before melting is the same as the mass of the water after melting, thus demonstrating the conservation of matter during a physical change (the transition from solid to liquid).
