A gaseous sample consisting of 1.00mol molecules is described by the equation of state pV_m =RT(1+Bp). Initially at 373K, it undergoes Joule–Thomson expansion from 100 atm to 1.00 atm. Given that C_p,m = 5/2 R, μ =0.21K atm⁻¹, B=−0.525(K/T) atm⁻¹ and that these are constant over the temperature range involved, calculate ΔT and ΔS for the gas.
