Question

why is relative dendity is taken at 4°C of water??

Answer 1

When the ice melts to liquid water, the structure collapses and the density of the liquid increases. At temperatures well above freezing, the molecules move faster and get further apart. The density decreases as temperature increases. ... Thus, the density of water is a maximum at 4 °.
