Question
A system is taken from state a to state c by two paths adc and abc as shown in the figure. The internal energy at a is ${U_a} = 10\,J$. Along the path adc the amount of heat absorbed dQ1 $=$ 50 J and the work obtained dW1 $=$ 20 J whereas along the path abc the heat absorbed dQ2 = 36 J. The amount of work allong the path abc is
