KJTIO1e AJ/I1IO) One mole of an ideal gas initially at 300 K and a pressure of 10 atm undergoes adiabatic expansion. () reversibly (11) irreversibly against a constant external pressure of 2 atm until the final pressure becomes equal to the external pressure. Find the value of ASvstem for (1) and (i) in the terms of R (heat capacity at constant volume is Cv= 1.5 R). Calculate the AH and AS for the nrocess .

    eduncle-logo-app

    ques ke according hi range milenge

    eduncle-logo-app

    so tensn mt lo reshav

    eduncle-logo-app

    sir entropy formula me beech me negative sign hoga

    eduncle-logo-app

    nhi reshav sahi hai

    eduncle-logo-app

    why reversible prcoess is zero ?

    eduncle-logo-app

    why we take minus 0.38 ? log (300/204) = 0.38
