• On heating from 0oC, the density of water increases up to 4oC and then decreases beyoud 4oC.

• When we heat water from 0∘C, we know that on heating, the volume of water decreases as the density of water decreases. But we can see this effect of decreasing volume and increasing density, till 4∘C, and the reason is because of the density of ice is maximum at 4∘C.

Answer:

water expand as the temperature. so density decreases
