Product description
When the state of oxygen changes in a polytropic process, the specific heat capacity of this gas is cn = -0.3 kJ/(kg•K). Mass of oxygen m = 4 kg. Determine the change in internal energy, the change in entropy and the work done if the initial parameters of oxygen are p1 = 5 • 105 Pa and T1 = 350 K and in the process under consideration 100 kJ of heat was supplied to the gas.
