GENERAL KNOWLEDGE

Detailed explanation-1: -Water has its maximum density of 1g/cm3 or 1000kg/m3 at 4∘C. When the temperature changes from either greater or less than 4 degrees, the density will become less than 1g/cm3. Water has the maximum density of 1g/cm3 only when it is pure water.

Detailed explanation-2: -In case of water, the volume is minimum and density is maximum at 4∘C, whether the temperature is increased or decreased the volume of water increases and density decreases. This behaviour of water is called the Anomalous Expansion of Water.

Detailed explanation-3: -Density of water at 4°C in S.I. units is 1000 kgm-3.

Detailed explanation-4: -Answer: Solution: The density of water at 4°C is 1.0 g c m − 3 g cm^-3 g cm−3.
