Answer» A monoatomic ideal gas undergoes a process in which the ratio of `P` to `V` at any instant is constant and equals `1`. `(P)/(V) =` constant `PV^(-1) =` constant `PV^(gamma) =` constant `gamma =-1` Monatomic gas: `C_(V) = (3)/(2)R` Molar heat capacity `= C_(V) +(R )/(1- gamma)` `= (3)/(2)R +(R )/(1-(-1))` `=(3)/(2)R +(R )/(2) = (4R)/(2)` |
