Question

As liquid water freezes, the molecules arrange themselves in a way that takes up more space than liquid water. What would most likely occur if the arrangement of frozen water molecules required less space than that of liquid water molecules? (2 points)

The density of ice would be greater than the density of liquid water, and ice would not float.

Ice would form in layers, and liquid water would get trapped in between the layers.

Liquid water would have a higher specific heat, making it less likely to undergo vaporization.

The freezing point of water would decrease, making ice more difficult to for

Answer 1

The answer would be A. When water freezes, it gets more space as a solid than it does as a liquid. Similar number or particles, but it will get more space and is therefore less dense. If water, when it froze, will get less space than water when it was liquid; meaning that the solid water would be more dense than the liquid water. Therefore it would sink to the bottom.

Answer 2

The appropriate answer is A. the density of ice would be greater than the density of liquid water and so ice would not float. Density can be defined as mass per unit volume. Any substance whose mass is great and occupies a relatively small volume is going to be dense.

Water expands by nine to ten percent when it freezes and this expansion increases the space occupied or the volume and so the density of ice is less than water.
