One mole of ideal monatomic gas undergoes the cycle, consisting of an isothermal process AB at temperature 400 K, an isobaric process BC, and an isometric process CA (between pressures of 100 kPa and 200 kPa). The work done by the gas during the isothermal process is 2305 J.
(a) Find the volumes VA = VC and VB, and the temperature TC.
(b) Find the work done for the entire cycle.
(c) Find the amounts of heat for each of the three processes.
(d) Find the eciency of this heat engine.
