Question

PLEASE HELP ME, PLEASE!!!

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.

There are a few things you could do, that would help.. type that into your search engine, sometimes in the results, there will be results that give answers to your question.. find a science helping app. There are a lot of apps that can help with your homework!! always come back on here. I would recommend coming here last. A lot of people on here give the wrong answers.. just try to figure it out yourself. OR contact your teacher. I have personally set up a meeting with my teacher, and it helped soooo much!!!
