A gas, initially at T=500 K, undergoes a Joule-Thompson (constant enthalpy) expansion from P=10 atm to P=1 atm.
A) Prove that (dT/dP)H is equal to: (1/Cp)[T(dV/dT)P – V] (You may assume this expression is valid for parts B and C, even if you are unable to prove it.) B) Find an expression for (dV/dT)P for this gas, in terms of P, T and known constants, assuming it follows the equation of state: V = (RT/P) + aT2P2 For full credit your answer should be an algebraic equation—all derivatives should be evaluated. C) Assuming the heat capacity of the gas is constant at Cp=5R, and that ‘a’ is constant at 2x10-7 L mol-1K-2atm-2, find the final temperature of the gas.
