Which procedure could be used to demonstrate that matter is conserved during a physical change?
O Find the mass of a piece of ice. Let the ice melt. Find the mass of the liquid water.
O Find the mass of a cup of water. Boil the water. Find the mass of the water that remains.
O Find the mass of an apple. Cut the apple and remove the core. Find the mass of the remaining apple.
O Find the mass of a raw egg. Cook the egg. Find the mass of the cooked egg.
All of the given procedures could be used to demonstrate that matter is conserved during a physical change. However, the most suitable procedure to directly demonstrate the conservation of matter would be:
- Find the mass of a piece of ice. Let the ice melt. Find the mass of the liquid water.
This procedure would involve measuring the mass of the ice and then, after it melts, measuring the mass of the resulting liquid water. If matter is conserved during the physical change, the mass of the liquid water should be equal to the mass of the ice.
