NEET Physics Thermal Expansion Assertion Reason Question
Assertion (A): The coefficient of volume expansion is approximately three times the coefficient of linear expansion for the same substance. | Reason (R): A cube of side length l will have a fractional volume change that is directly proportional to the square of its linear expansion.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
Assertion is true as per the relation . However, the reason is false because the fractional volume change is proportional to the linear expansion, not its square.
