Consider a thermodynamic system consisting of 3 mol of an ideal gas occupying
0.03 m3
volume at 300 K temperature. Determine its initial pressure. For this
gas, γ=1.4. It undergoes the following processes:
i) It is compressed to 0.01 m3
volume isothermally. Determine the pressure of the
gas.
ii) then it is allowed to expand adiabatically, till it attains 1 atm pressure. Determine
the final volume. (1 atm = 101325 Nm-2
)
Draw a labeled indicator diagram of these processes.
