Find the mass of an apple. Cut the apple and remove the core. Find the mass of the remaining apple.

Answer 1

To demonstrate that matter is conserved during a physical change, the best procedure from the options provided is:

**Find the mass of a piece of ice. Let the ice melt. Find the mass of the liquid water.**

This procedure effectively shows that, during the physical change of melting (from solid to liquid), the total mass before and after the change remains the same, thereby demonstrating the law of conservation of mass.
