Question

Here is a description of a familiar course of events; A glass bottle filled with water was placed in the freezer. Sometime later it was found that the water had frozen and the glass bottle had cracked open.

In answering the following questions, cite evidence from the above description and experiments you have performed in the laboratory.

Upon freezing, did the volume of the water increase, decrease, or remain the same?

Upon freezing, did the mass of the water increase, decrease, or remain the same?

need explanation!

Answer 1

Mass will always be constant for a closed system. We know mass = density x volume.

and density of ice is less than that of water, therefore volume of ice must be more than that of water so that mass remains constant.

upon freezing, volume increased.

upon freezing, mass remained same.
