Question

If a tray containing 300 g of water is placed in the freezer to make ice, what is the mass of the ice after the water freezes?

A) 300 g
B) 600 g
C) 900 g
D) 150 g

Answer 1

The mass of ice will be the same as the mass of the water before freezing, which is 300 g, due to the conservation of mass.

Step-by-step explanation:

If a tray containing 300 g of water is placed in the freezer to make ice, the mass of the ice after the water freezes will remain the same, which is 300 g. This outcome is due to the law of conservation of mass, which states that mass cannot be created or destroyed in an isolated system. The transformation from water to ice is a physical change and does not involve the gain or loss of mass. Therefore, the correct answer is A) 300 g.
