Question

Study the graph given below and select the correct statement:

• A. When water is cooled to $4{}^{o}C$, it contracts
• B. At $0{}^{o}C$, water freezes
• C. The volume of ice is more than the volume of water at $0{}^{o}C$
• D. All of these

Answer 1

The correct option is D All of these

When water is cooled, it contracts till it reaches around $4{}^{o}C$, after which water starts to expand. This is why water has the highest density at around $4{}^{o}C$. This means that ice at $0{}^{o}C$ occupies more volume than that of water at $0{}^{o}C$.
