Question

Consider the following reversible processes and choose the correct answer(s) from the options given below:

5 moles of Argon at 298K in state x (P = 10 atm) undergoes isothermal process to state y (P = 1 atm).
From state x, there is an adiabatic process (q = 0) to state z (5 moles of Argon at 'T' K).
From state z, there is a process to state y.
