Assertion The density of water remains constant as it is cooled from room temper
Assertion The density of water remains constant as it is cooled from room temperature until its temperature reaches \( 4^{\circ} C \) Reason Below \( 4^{\circ} C \),the density increases.
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Both Assertion and Reason are incorrect
Step-by-step solution
Water exhibits anomalous expansion: its density increases when cooled from room temperature to 4°C, contradicting the assertion that it remains constant. Below 4°C, density decreases, not increases, so the reason is also false. Hence both statements are incorrect.
