10 kg gas is contained in a vertical piston-cylinder assembly by a piston weighing 40 Kg and having a face area of 60 cm2. The atmosphere exerts a pressure of 101.3 kPa on the top of the piston. An electrical resistor transfers energy to the gas in the amount of 5.3 kJ as the elevation of the piston increases by 0.6 m. The piston and cylinder are poor thermal conductors and friction can be neglected. 1. Sketch a figure of the process 2. Determine the change in internal energy of the gas, in kJ, assuming it is the only significant internal energy change of any component present.
