Assertion (A): The coefficient of volume expansion has dimension \( \mathrm{K}^{-1} \).
Reason(R): The coefficient of volume expansion is
P
defined as the change in volume per unit volume per unit change in temperature.
(1) If both assertion and reason are true and the reason is the correct explanation of the assertion.
(2) If both assertion and reason are true but reason is not the correct explanation of the assertion.
(3) If assertion is true but reason is false.
(4) If the assertion and reason both are false.
