Question

Water is heated from $0^{o}C$ to ${10}^{o}C$. How does the density of water change with temperature?

• A. On heating, density of water increses.
• B. On heating from $0^{o}C$, the density of water increases up to $4^{o}C$ and then decreases beyoud $4^{o}C$.
• C. On heating , density of water decreases
• D. Density of water is independent of temperature

Answer 1

Answer: (B)

On heating from $0^{o}C$, the density of water increases up to $4^{o}C$ and then decreases beyoud $4^{o}C$.

On heating from $0^{\circ }C$, the density of water increases up to $4^{\circ }C$ and then decreases beyond $4^{\circ }C$
