Class 11 NEET Physics Thermodynamics and Kinetic Theory

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 Ua=10J. Along the path adc the amount of heat absorbed dQ1=50J and the work obtained dW1=20J whereas along the path abc the heat absorbed dQ2=36 J. The amount of work along the path abc is
