• # question_answer A monatomic gas undergoes a process given by $2dU+3dW=0,$ then the process is A) isobaric B) adiabatic C) isothermal D) none of these

 [b]$dQ=dU+dW=dU-\frac{2dU}{3}=\frac{dU}{3}$ $=\frac{1}{3}n{{C}_{\upsilon }}dT=\frac{1}{3}n\frac{3}{2}RdT=\frac{nRdT}{2}$ $\Rightarrow$            $C=\frac{1}{n}\cdot \,\frac{dQ}{dt}=\frac{R}{2}$ Which is not equal to 0, infinity or 5R/2.
