Question

Water from $4^{0}C$ to $0^{0}C$

• A. expands
• B. contracts
• C. starts to turn into ice
• D. none of these

Answer 1

Answer: (A)

expands

The volume decreases normally from room temperature down to $4^{0}C$, just like we would expect, but as the temperature falls further, the molecules tend to form hydrogen bonds, and push away neighbouring molecules that are too close for comfort.

So as water goes from $4^{0}C$ to $0^{0}C$ , it expands

therefore option $A$ is correct
