NEET Physics Thermal Expansion Assertion Reason Question
Assertion (A): A steel rod will experience compressive strain if its ends are fixed rigidly and its temperature increases. | Reason (R): The increase in temperature causes the steel rod to expand, but the fixed ends prevent this 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
According to the NCERT context, thermal expansion causes a change in dimensions when temperature changes. If the rod's ends are rigidly fixed, expansion is prevented, resulting in compressive strain.
