Question

Water in a container is heated from $0^{\circ }$ to ${10}^{\circ }C$. Its volume :

• A. increases for the full given range (from $0^{\circ }$ to ${10}^{\circ }C$)
• B. decreases up to $4^{\circ }$, then increases
• C. increases up to $4^{\circ }C$, then decreases
• D. decreases for the full range (from $0^{\circ }$ to ${10}^{\circ }C$)

Answer 1

The correct option is B decreases up to $4^{\circ }$, then increases

As water has maximum density at $4^{o}C$. So going from $0^{o}C$ to ${10}^{o}C$.

First its volume decreases upto $4^{o}C$, making density maximum and then increases to lower the density again.
