Question

At 4${}^{\circ }C$, the density of water is _____ $kg/m^3$

• A. 1000
• B. 1
• C. 200
• D. 0.1

Answer 1

The correct option is A 1000

Graph showing variation of density of water with temperature in the $0^{o}C$ to ${10}^{o}C$ range, it is found that the density decreases when water at $4^{o}C$ is heated further. The density also decreases when water at $4^{o}C$ is cooled further.

Hence we can say water has maximum density at $4^{o}C$. The density of water is $1g/c{m}^3$ or $1000kg/m^3$ at $4^{o}C$.
