10 kg gas is contained in a vertical piston-cylinder assembly by a piston weighing 40 Kg and having a face area of 60 cm?. 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.

An insulated cylinder fitted with a movable piston to maintain constant pressure initially contains 100 g of ice at -10 C. Heat is supplied to the contents at a constant rate by a 100 W heater. Make a graph showing temperature of the cylinder contents as a function of time starting at t = 0, when the temperature is -10 C and ending when the temperature is 110 C. Let c = 2.0 kJ/kg Kfor specific heat of ice from -10 to 0 C and of the steam from 100 to 110 C. The specific heat of water between 0 C and 100 C is c = 4.18 X 103 J/kg K. The value of Lv = 2257 X 103 J/ kg and Lf = 333.5 X 103 J/kg.
