               1           It is known that curves A, B, C are Isobaric, Isothermal, Adiabatic process then when one is
                           correct



















                           (a) A - Adiabatic, B - Isothermal,, C - Isobaric
                           (b) A- Isothermal,, B - Adiabatic, C - Isobaric
                           (c) A - Isobaric, B - Isothermal C - Adiabatic
                           (d) None of these
               2           An ideal gas taken round the cycle ABCA as shown in PV diagram
































               3           The coefficient performance of a refrigerator is 5. If the temperature inside the freezer is -
                           20℃, calculate the heat rejected to the surrounding
                           (a) 11℃
                           (b) 41℃
