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...

Assume air can be modeled as an ideal, diatomic gas. Given n moles of air at temperature T0 and pressure p0, how much energy must be expended as work to compress it to one tenth of its original volume, if a) the compression occurs along an isotherm? b) the compression occurs along a reversible adiabatic path? c) Evaluate your results to parts (a) and (b) for n = 5.00 mol, T0 = 20.0 ◦C, and p0 = 1.00 atm.

Let us first examine the behavior of an ideal gas when we force the volume to be a value of our choosing. We can examine how changes to the absolute temperature and number of moles affect the pressure of the gas particles (by selecting pressure with Rspd such that pressure cannot be controlled). Assume that 0.03 mol of helium at a temperature of 275.00 K occupy a volume of 1.40 L. Use the Run Experiment tool in the Simulation to...
A gas cylinder containing carbon dioxide, CO2, 85% by volume, and nitrogen, N2, 15% by volume has a volume of 2.2 m and is kept at a temperature of 20°C.

Q5. An efficiency consultant is studying the power stroke of a four-stroke engine and determines the following: As the piston is forced down, the mixture of combustion products and air undergoes an adiabatic expansion. The engine is running at 3,100 cycles/min. The gauge pressure immediately before the expansion is 25.0 atm. The volumes of the mixture immediately before and after the expansion are 50.0 cm3 and 400 cm3, respectively (figure below). The time interval for the expansion is one-fourth the...
