NEET Physics Thermal Expansion Assertion Reason Question
Assertion (A): The coefficient of volume expansion of copper is significantly higher than that of glass. | Reason (R): The coefficient of volume expansion (α_v) is three times the coefficient of linear expansion (α_l).
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
Copper has a higher coefficient of linear expansion compared to glass, and α_v is indeed three times α_l, which explains the assertion.
