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.

Oxygen (molar mass 32 kg/kmol ) expands reversibly in a cylinder behind a piston at a constant pressure of 3.129 bar. The volume initially is 0.011 m3 and finally is 0.0327 m3; the initial temperature is 16.3 0C. Calculate the heat supplied during the expansion in the correct unit to two decimal places. Assume oxygen to be a perfect gas and take the specific heat at constant pressure as = 0.917 k J / k g K and molar gas constant as = 8,314 J / kmol K
A student struggled with his first midterm exam and is slightly angry. For this reason he drops a 10 kg object on the good teacher from a height of 5 m. When seeing the object fall to the ground, the teacher asks the logical question: How much will the internal energy of the box have increased after hitting the ground? If the specific heat of the box is cp = 3 kJ / kg.K How much will the temperature of the box have increased?
