Reuben wanted to test the Law of Conservation of Mass using different stages of water. He first measured the mass of a beaker with three ice cubes. After one hour, he measured the mass of the beaker with liquid water. Reuben observed that both measurements were almost the same. What would be a good explanation for Reuben observation?
A: The amount of water as ice increased when the water turned into liquid.
B: The mass of the beaker increased with the change in temperature, so it balanced the amount of water in the change of state.
C: There is no mass in water as solid or liquid, so only the beaker mass was measured.
D: The initial amount of water in the solid state (ice) was the same amount of water in the liquid state measured at the end, except for some water that might be evaporated.
