Question

When water is heated from $0^{\circ }C$ to ${10}^{\circ }C$, its volume ______.

• A. increases
• B. decreases
• C. does not change
• D. first decreases and then increases

Answer 1

The correct option is D first decreases and then increases

Density of water is maximum at $4^{o}C$. So during heating from $0^{o}C$ to ${10}^{o}C$, its density increases at first and then it decreases resulting in the decrease in volume at first and then increase in its volume.
