Q25. 0.5 kg of air at pressure of 2000 kN/m2 occupies 0.1 m' and from this
condition it is expanded to 1.4MN/m2 according to the law PV.25 = C.
And then heated at constant volume to pressure of 2 MN/m2. Calculate the
work, heat transfer and the change of entropy during these processes.
Take, C= 1.006 kJ/kg K, R= 0.287 kJ/kg K.
