1.	When a system is taken from state i to state f along the path iaf, it is found that `Q=50 cal and W=20 cal`. Along the path ibf `Q=36cal`. W along the path ibf is
Answer» From first law of thermodynamics, `dQ=dU+dW` For path iaf, `50=DeltaU+20rArrDeltaU=30` cal For path ibf, `dW=dQ-dU=36-30=6` cal
