Answer 1

Answer:

When temperature is increased after 0 ° C , generally liquids expand but water contracts.

Thus volume of water decreases from 0 to 4 ° C and is minimum at 4° C.

Answer 2

Generally solids expand after melting. Their density decreases.

But ice contracts when it melts into water. It's volume decreases and density increases. That's why ice floats on water...

Hope your doubt is cleared.

Have a great day :)
