4. Suppose we change the pressure of an ideal gas at constant temperature. How is the corresponding AG related to its AS for the same process? For example, are they proportional to each other, and - if so - what is the proportionality constant?
105Pa, initial temperature T-300K, and an initial 1. An ideal gas with initial pressure 2 volume V - 1m3 expands isothermally to a final volume of 2m3. Then, the gas returns to its initial state, first by constant pressure (isobaric) contraction, and then by a change at constant volume (isochoric) a) Draw a PV diagram of this process. What's the total change in thermal energy of the entire process? b) What's the work done by the environment on the gas?...

The ideal gas law (PV=nRT) describes the relationship among pressure P, volume V, temperature T, and molar amount n. Fix n and V When n and V are fixed, the equation can be rearranged to take the following form where k is a constant: PT=nRV=k or (PT)initial=(PT)final This demonstrates that for a container of gas held at constant volume, the pressure and temperature are directly proportional.The relationship is also called Gay-Lussac's law after the French chemist Joseph-Louis Gay-Lussac, one of...
Because (∂H/∂P)T =−CPμJ−T, the change in enthalpy of a gas expanded at constant temperature can be calculated. To do so, the functional dependence of μJ−T on P must be known. Part A Treating Ar as a van der Waals gas, calculate ΔH when 1 mole of Ar is expanded from 329 bar to 1.68 bar at 375 K. Assume that μJ−T is independent of pressure and is given by μJ−T=[(2a/RT)−b]/CP,m, and CP,m=5/2R for Ar. The van der Waals parameters a...
The pressure, P in atmospheres (atm), of an ideal gas can be expressed as a function of volume, V in liters (L), and temperature, T in kelvin (K), is P(V, T) = nRT/V where n = 1 mol and R 0.08 are constants. Suppose the current volume and temperature of a gas behaving according to the ideal gas law are: V = 5 L and T = 300 K.

Example 20.9 Consider two quasi-static processes that take an ideal gas containing N particles from an initial state of (Pi, Vi) to a final state (Pr,V). Process A is a one step isentropic compression. Process B has two steps: an isochoric pressure increase followed by an isobaric compression.
