Assertion: On heating, a solid usually changes to a liquid and the liquid on further heating changes to the gaseous state.
Reason: Arrangement of constituent particles is different in solid, liquid and gaseous state.
A
If both assertion and reason are true and reason is the correct explanation of assertion.
B
If both assertion and reason are true and reason is not the correct explanation of assertion.
C
If assertion is true but reason is false
D
If both assertion and reason are false.
Answer
Option B
Explanation
Solution
The assertion is true. The reason is also true as it states the difference in particle arrangements. However, the reason does not explain the process of phase change due to heating; it only describes the inherent structural differences.
