Assertiobn : Ratio of isothermal bulk modulus and adiabatic bulk modulus for a monoatomic gas at a given pressure is `3/5`.
This ratio is equal to `gamma =C_(p)/C_(v)`.
A. (a) If both Assertion and Reason are true and the Reason is correctn explanation of the Assertion.
B. (b) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
C. If Assertion is true, but the Reason is false.
D. If Assertion is false but the Reason is true.
