Please give detailed explanation for final part. Thanks.
Reversible adiabatic expansion of ideal gas (This question involves working through the final section of lecture 3) Explain why the first Law for an reversible adiabatic process gives AU = -PdV, and why this equation doesn't hold for the Joule expansion. Assuming that for an ideal gas U = CVT, prove that the First Law leads to the statement that PVY is constant in a reversible adiabatic process. A container of Helium...

Problem # 2 135 Points Polytropic Processes A piston-cylinder undergoes a constant pressure expansion process followed by an adiabatic compression. The adiabatic compression can be modeled as a polytropic process PVn constant with a volume exponent n 1.4. At state 1 the pressure of the system is P1 60 psi, the volume is Vi 8.868 ft3 and the internal energy U 1630.6 BTU. The work output during the constant pressure process is W2-75.2 BTU and the heat transfer input for...

The pressure P and volume V of a certain amount of steam in an adiabatic process (a process in which the heat in the system does not change due to proper insulation) fairly follows the equation PVY K where y and K are constants. In an adiabatic experiment, the volume of a certain amount of steam confined in a tank is gradually increased, resulting in a decrease in gas pressure. Using the above equation and linear regression, find the values...
