physical problems

2)a)false,consider there is no change of state,ie all state parameters remain const,here it is also an isochoric,adiabatic process.
b)false.Universe can be considered to be an isolated system.
c)True.
d)false.In a cyclic process,part can be considered spontaneous and the other non-spontaneous or forced.Hence there should be some some work,heat interaction that will change the state of surroundings.

2) i think c) d) are correct

c)cyclic process means that the initial state and final states are same.

aditya but they have asked for the state of surroundings.

2nd law states:
It is impossible to construct a machine operating in cycles [ie cyclic process]that will convert heat into work without producing any other changes.

i didnt see surrounding.

Thanks Swaraj for second.
