Water on heating from 0 ∘C to 4 ∘C contracts and on further heating it expands.
A decrease in temperature caused the water molecules to lose energy and slow down, which results in water molecules that are closer together and a decrease in water volume. When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense.
