Specific heat of a van der waals gas
WebJun 13, 2024 · Since the process is adiabatic, any heat taken up by the upstream gas must be surrendered by the downstream gas, so that q1 + q2 = 0. For the process of moving the mole of gas across the plug, ΔE = ΔE1 + ΔE2 = − ¯ E1 + ¯ E2 = q1 + q2 + w1 + w2 = P1¯ V1 − P2¯ V2 from which ¯ E1 + P1¯ V1 = ¯ E2 + P2¯ V2 or ¯ H1 = ¯ H2 WebIf the analytical solution of the van der Waals equation is known, one can calculate the different thermodynamic properties of real gas. 2.
