Equation of state selection
WebEQUATION OF STATE Consider elementary cell in a phase space with a volume ∆x∆y∆z∆px ∆py ∆pz = h3, (st.1) where h = 6.63×10−27erg s is the Planck constant, ∆x∆y∆z is volume in ordinary space measured in cm3, and ∆px ∆py ∆pz is volume in momentum space measured in (g cm s−1)3.According to quantum mechanics there is enough room … WebLet the system settle down to an equilibrium state under the constraint . In this state, the two sides should have the same temperature T. Given the ideal gas equation of state PV = Nk BT, the two sides will not have the same pressure, unless = L=2. This means that, in general, force must be applied on the separator to maintain the constraint .
