Two moles of gas are confined in a piston–cylinder device.
Initially, the temperature is at 300 K and the pressure is 1 bar.
The gas is compressed isothermally to 5 bar. If the ideal gas heat
capacity is C ig P = 7R/2, find Q, W, ?U, ?H, and ?S if:
(a) the gas is ideal, or
(b) the gas satisfies the van der Waals equation of state with a
= 5.0 × 106 bar · cm6/mol2 and b =...
