Step-by-step explanation:

When I used your answer, I got it wrong. Oh, the mockery, the pain, the sorrow...

Answer 2

Water has its maximum density at 4 degree C. If you cool or heat water from 4degree C, the density will decrease. Minimum density will be at 0 C if you are cooling it from 4 C. Minimum density will be at 100 C if you are heating it.
