1. A gas (1.00 mol) obeying the following equation of state (EOS) is compressed from P 1.00 atm to P= 2.00 atm isothermally (300K) and reversibly: n RT P V nb (a) [5 points] Calculate the entropy change, AS. (b) [10 points] Calculate the amount of heat (q) and work (w) involved. What does the total energy change (AU) tell you about the internal energy of this system?
A gas is compressed at a constant pressure of 0.800 atm from 6.00 L to 2.00 L. In the process, 370 J of energy leaves the gas by heat. (a) What is the work done on the gas? J (b) What is the change in its internal energy? J

Question 4 (40 points) Assume that a non-ideal gas can be described by the following EoS, where a and b are constant: (p + a)V -RT The gas is isothermally and reversibly expanded from (p, Vi) to (p2, V2) Determine the following thermodynamic properties for this process: W, Q, AU, ΔΗ, ΔΑ, AG, ASgas and ΔSsurroundings.
Please answer all three parts and show work. Thank you!
1. An ideal gas assumes molecules are point particles and do not interact with each other. In reality, molecules occupy space! To correct for this, the ideal gas equation of state is adjusted to take the volume occupied by the molecules into account for a real gas: PV = nRT or P = nRTV is modified to P = nRT/(V-nb) (IDEAL GAS) (REAL GAS Where "b" is related to the...
Suppose 2.00 mol of an ideal gas of volume V =3.50m^3 at T = 300K .allowed to expand isothermally to V = 7.00m^3 at T = 300K. Determine (a) the work done by heat added to the gas. and (c) the change in internal energy of the gas. (Ans: 3.6 times 10^3, J, 0, 3.6 times 10^3J)
