Question

the density of water is maximum at which temperature.explain why?

Answer 1

Water never has an absolute density because its density varies with temperature. Water has its maximum density of 1g/cm3 at 4 degrees Celsius. When the temperature changes from either greater or less than 4 degrees, the density will become less then 1 g/cm3.

Answer 2

HEY FRIEND,
YOUR ANSWER IS,

The maximum density of water occurs at 4 °C because, at this temperature two opposing effects are in balance.
Explanation: In ice, the water molecules are in a crystal lattice that has a lot of empty space.
