3: A ges contained in a cylinder is compressed from 1 MPa and 0.05 m² to 2 MPa. Compression is governed by pV4 = constant. Internal energy of gas is given by U = 7.5 pV - 425, kj where p is pressure in kPa and V is volume in m'. Determine heat, work and change in internal energy assuming compression process to be quasistatic. Also find out work interaction, if the 180 kJ of heat is transferred to system between same states. Also explain, why is it different from above.
