Answer:
When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume. When water decreases in volume, it becomes more dense.

Explanation:
On cooling
The object contracts and the volume decreases. This is because with less heat, molecules vibrate less and the atoms get closer.
On heating
The object expands and volume increases. With more energy, the atoms vibrate faster and move away from each other
water is exception because it makes different kind of bond in those bods there is some space left
