3. The internal energy of a certain substance is given by the following equation: u = 3.56 pv + 84 where u is given in kJ/kg ; p is in kPa and v is in m'/kg. A system composed of 3 kg of this substance expands from an initial pressure of 500 kPa and a volume of 0.22 m' to a final pressure of 100 kPa in a process in which pressure and volume are related by pv¹2 = constant. If the expansion is quasi-static, find the internal energy and the heat transfer during the process.
