WebThe data yielded the molecular weight, radius of gyration, and second virial coefficient of α-crystallin at different temperatures. The second virial coefficient increased with increasing temperature. Both the enthalpy and entropy of solution of α-crystallin are positive. The Flory thetatemperature was found to be 271 K. WebJan 15, 2024 · This should make some sense given that the first virial coefficient provides most of the deviation from the ideal gas law, and so it must vanish as the gas …
Web2. Virial coefficients of hard linear tangent spheres The model of HLTS consists of m hard spheres in contact in a linear rigid configuration, as illustrated in figure l(a). We have evaluated the first five virial coefficients of HLTS with m ranging from m = 3 to m = 7 by the method of Ree WebNov 15, 2024 · The first four virial coefficients are given, in the graphical representation, as follows [16]: (1) (2) (3) where T is temperature and V is the volume. In the diagrams, the filled circles represent integration variables (position vector of molecules), and edges the Mayer-function, f ≡ e − 1 = exp( − βu ) − 1, where β = 1/ k B T , k B ...
