23 Anomalous Behaviour of Water MCQs from Chemistry, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Water expands when cooled below 4°C and when it freezes, giving liquid water its maximum density at 4°C. The explanation depends on hydrogen bonding and the open structure of ice, which makes ice less dense than water and allows it to float.

- A. 2°C
- B. 4°C
- C. 0°C
- D. <0°C
Explanation: When water is at 0 ° C , it takes a cage-like structure, and thus the volume increases which results in the density decrease.
Correct answer: 4°C- A. Colorless
- B. Is a bad conductor
- C. Does not expand linearly
- D. Has a low boiling point of 100oC
Explanation: The correct answer is that water does not expand linearly. Water's anomalous expansion, particularly its contraction from 0°C to 4°C and…
Correct answer: Does not expand linearly- A. Lighter
- B. Highest
- C. Heavier
- D. Heaviest
Explanation: Water has the highest density at 4 degree C as the cage-like structure which forms when water freezes starts breaking.
Correct answer: Heaviest
