A monoatomic gas at a pressure P, having a volume V expands isothermally to a volume 2V and then adiabatically to a volume 16V. The final pressure of the gas is : (take \(\gamma = \frac{5}{3}\)) |
64 P 32 P \(\frac{P}{64}\) 16 P |
\(\frac{P}{64}\) |
For isothermal process : PV = constant PoV = P'(2V) ⇒ P' = \(\frac{P_o}{2}\) For adiabatic process : PV\(\gamma\) = constant P'(2V)\(\gamma\) = P'' (16V)\(\gamma\) For monoatomic gas : \(\gamma = \frac{5}{3}\) P'' = Po/64
