Two mole of ideal gas, is compressed adiabatically in a piston/cylinder device from 2 bar and 25oC to 7 bar. The process is irreversible and requires 25% more work than a reversible, adiabatic compression from the same initial state to the same final pressure. What is the entropy change of the gas? Assume Cv=(5/2)R in this calculation.

Problem 6.030 SI Air is compressed adiabatically in a piston-cylinder assembly from 1 bar, 300 K to 4 bar, 600 K. The air can be modeled as an ideal gas and kinetic and potential energy effects are negligible. Determine the amount of entropy produced, in kJ/K per kg of air, for the compression. What is the minimum theoretical work input, in kj per kg of air, for an adiabatic compression from the given initial state to a final pressure of...

Question 2 One mole of an ideal gas, initially at 30 C and 1 bar is changed to 130 °C and 10 bar by using two different mechanically reversible processes: 2.1 The gas is first heated at constant pressure until its temperature is 130 °C and then compressed isothermally to 10 bar. 2.2 The gas is first compressed isothermally to 10 bar and then heated at constant pressure to 13°C Calculate Q, W, AU, and AH for each case. Take...
7.) One mole of an ideal gas is contained in an insulated piston-cylinder arrangement in an initial state T, P,V. The gas is allowed to expand adiabatically and irreversibly against a constant external pressure P. until a point is reached where the internal pressure becomes equal to Po. If C for the gas is constant and equal to 1.5 R, derive an expression giving the final temperature of the gas in terms of P., V, T, and R.
