When a system is taken from state i to state f alone the path iaf, it is found that Q=50 cal and W=20 cal. Along the path ibf, Q=36 cal (figure) (a) What is W along the path ibf ? (b) If W=-13 cal for the curved return path f i , what is Q for this path ? (c) Take U_(i)=10 cal. What is U_(f) ? (d) If U_(b)=22 cal, what is Q for the process in and for the process bf ?

When a system is taken from a state i to a state f in Figure, along the path iaf , we find DeltaQ=50cal and DeltaW=20cal while during the path ibf , DeltaQ=36cal . If U_i=10cal . (a) What is U? What is W along the path ibf ? (c ) If W=-13cal , along the curved path fi , what is DeltaQ for this path? (d) If U_b=22cal , what is DeltaQ for the process ib ? for bf ?
