Answer:
-An increase in temperature caused the water molecules to gain energy and move more rapidly, which resulted in water molecules that are farther apart and an increase in water volume.
When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense.
-Heat can affect matter by causing it to change state. The cool liquid then cools the surface on which it is resting.
