3 moles of an ideal diatomic gas undergoes the three process cycle as depicted in the figure below, The cycle is composed of an isobaric, isovolumetric, and isothermal process. For the given parameters P,=P, =1.4 10 Pa and V-1 m, V,- V-0.6667 m calculate the following. (Take the universal gas constant as R- 8.314 J-mol"1.K-) a) The pressure p. Pa b) The net work done by the gas W, net" e) The heat entering the cycle Q= d) The thermal efficiency of the cycle (in percent): e =
