Question

When the water is heated from $0$ to $10$, its volume

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

Answer 1

The correct option is D first decreases then increases

Water has a unique property of anomalous expansion. When water is heated from $0^{o}C$ to $4^{o}C$ it contracts continuously instead of expanding. That means its volume decreases upto $4^{o}C$. When heated from $4^{o}C$ to ${10}^{o}C$, its expansion is normal like the expansion of other liquids.
