A system undergoes three quasi-static process sequentially as indicated in Fig. 1-2 is an isobaric process, 2-3 is a polytropic process with `gamma = 4//3` and 3-1 is a process in which `PV` = constant. `P_(2) = P_(1) = 4 xx 10^(5) N//m^(2), P_(3) = 1 xx 10^(5) N//m^(2)` and `V_(1) = 1 m^(3)`.
The heat transfer for the cycle is `Delta Q`, the change in internal energy is `Delta U` and the work done is `Delta W`. Then

A thermodynamic process is shown in Fig. The pressures and volumes corresponding to some points in the figure are P_(A) = 3 xx 10^(4) Pa V_(A) = 2 xx 10^(-3) m^(3) P_(B) = 8 xx 10^(4) Pa V_(D) = 5 xx 10^(-3) m^(3) In the process AB 600 J of heat is added to the system. The change in internal energy of the system in the process AB would be

In an isobaric process, Delta Q = (K gamma)/(gamma - 1) where gamma = C_(P)//C_(V) . What is K ?

A reversible heat engine carries 1 mole of an ideal monatomic gas aroung the cycle 1-2-3-1. Process 1-2 takes place at constant volume, process 2-3 take place at constant volume, process 2-3 is adiabatic, and process 3-1 takes place at constant pressure. Complete the values for the heat Delta Q , the change in internal energy Delta U , and the work done Delta , for each of the three processes and for the cycle as a whole.
