1.	A polytropic process for an ideal gas is represented by equation `PV^(n) = constant`. If g is ratio of specific heats `((C_(p))/(C_(v)))`, then value of n for which molar heat capacity of the process is negative is given asA. `gamma gt n`B. `gamma gt n gt1`C. `n gt gamma`D. none, as it is not possible
Answer» Correct Answer - B `C = R/(gamma-1) - R/(n-1) = (R(n-gamma))/((n-1)(gamma-1))` `C` is negative if `gamma gt n gt 1`.
