Question

What change in volume will be observed when temperature of water gradually increases from $0^{\circ }C$ to ${15}^{\circ }C$ ?

• A. Increase steadily
• B. Decreases steadily
• C. At first decreases then increases
• D. At first increases then decreases

Answer 1

The correct option is C At first decreases then increases

We know,

Density increase from $0-4^{0}C$ and decreases from $4^{0}C$ and further.

Density is maximum at $4^{0}C$

Density increases when volume decreases and vice versa.

Hence Volume first decrease and then increases.

Option $\text{C}$ is the correct answer
