Q2. Two kilograms of air within a piston-cylinder configurationexecute a Carnot power cycle between temperatures 750 K and 300 K.The isothermal expansion is associated with a heat input of 60 kJfrom the surroundings. The volume after expansion has occurredisothermally is 0.4 m3 . Assuming air behaves as an ideal gas,calculate: (i) thermal efficiency for the cycle (ii) pressure andvolume at the beginning of the isothermal expansion, in kPa and m3, respectively. (iii) the work and heat transfer for each of thefour processes, in kJ.
