Question

What happens to water when it freezes?

Answer 1

Explanation:

When an object undergoes a physical change (solid to liquid, decrease in temperature etc.), the mass of the object remains constant.

When water freezes, the water molecules vibrate closer to one another and there is less space between the molecules.

The same number of water molecules now occupy a smaller volume, therefore their density increases.

The correct answer is the 3rd option.

Answer 2

Answer:

Its  density decreases

Explanation:

water expands when it freezes making it less dense than before.
