The molar heat capacity for an ideal gas (i) Is zero for an adiabatic

1.	The molar heat capacity for an ideal gas (i) Is zero for an adiabatic process (ii) Is infinite for an isothermal process (iii) depends only on the nature of the gas for a process in which either volume or pressure is constant (iv) Is equal to the product of the molecular weight and specific heat capacity for any processA. (i),(iii)B. (ii),(iii)C. (iii),(iv)D. all
Answer» Correct Answer - D (i) Adiabatic process `DeltaQ=0` `DeltaQ=nCDeltaT=0impliesC=0` (ii) Isothermal process, `DeltaT=0` `DeltaQ=nCDeltaTimpliesC=(DeltaQ)/(nDeltaT)=(DeltaQ)/(nxx0)=infty` (iii) P: Constant `C=C_P=(gammaR)/(gamma-1)` V: constant `C=C_V=(R)/(gamma-1)` `gamma:` depends on nature of gas (iv) `C=Ms`
