The Figure Shows the PV Diagram for a Certain Thermodynamic

question 44

Short Answer

The figure shows the pV diagram for a certain thermodynamic process. In this process, 1500 J of heat flows into a system, and at the same time the system expands against a constant external pressure of 9.00 x 10⁴ Pa. If the volume of the system increases from 0.020 m³ to 0.050 m³, calculate the change in internal (thermal) energy of the system. If the internal (thermal) energy change is nonzero, be sure to indicate whether this energy change is positive or negative.
