Answers
Answer:
a)(property of matter)The diver is able to cut through water in a swimming pool. This observation shows that the matter has spaces between them so that the particles can move from one place to another to accommodate the body of the diver.
b)Water can exist in three different physical states. Water does exist in the form of ice or snow in the solid-state. Water exists as water vapour or steam, in the gaseous state and it exists in the form of water in its liquid state.
The density of ice is less than water. Liquids generally have lower density as compared to solids but ice floats on water. When water freezes to form ice, some empty spaces are created. As a result, volume increases for the same mass of water.
