space used(includes formatting): 0 / 30000
part f
as the water freezes, will its mass change? explain.

Explanation:

For Part E, using the same amount of water for each ice - shape ensures a fair comparison in experiments related to factors like melting time, surface - area to volume ratio effects, etc. For Part F, according to the law of conservation of mass, in a closed system, the mass of water remains the same when it freezes because no matter is added or removed during the phase change from liquid to solid.

Answer:

Part E: To ensure fair comparison in experiments.
Part F: No, because of the law of conservation of mass in a closed system.
