Question

Judy kept 250 grams of juice in the freezer. What is most likely the mass of the frozen juice formed and why?

250 g, mass remains same during physical change of freezing
500 g, mass of ice is twice the mass of juice
250 g, mass is conserved when matter is destroyed to form ice
200 g, mass of frozen liquid is less than mass of the original liquid

Answer 1

The answer is simple. It stays at 250 grams, because when the juice freezes, the volume shrinks down due to the amount of movement they are making, but the mass never changes. It obviously can't be the third answer 250 grams because the mass is conserved when the matter is destroyed to form ice. You can't destroy or create matter, as we can tell by the laws of conservation of matter, matter cannot be created nor destroyed. And there is no way that the mass would double in size.

Answer 2

Answer: Option A

Step-by-step explanation:

The juice of 250 grams will be the same in case of ice this is because the mass of the liquid will not change when there is a physical change in the state of matter.

The change in state of matter does not changes the mass of the substance. IF 250 grams of water is kept inside the freezer to get converted into ice, then the 250 grams of liquid will be 250 grams of ice.

hence, option A is correct.
