NEET Physics Thermal Expansion Assertion Reason Question
Assertion (A): The coefficient of volume expansion is three times the coefficient of linear expansion for the same material. | Reason (R): The increase in dimensions of a body due to temperature change is called thermal 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
The assertion is based on the relation αv = 3αl as given in the NCERT, while the reason defines thermal expansion broadly, not explaining the specific relation.
