A method for determination of the second virial coefficient of a pure gas is based on the Clapeyron equation and measurements of the latent heat of vaporization (ΔH^lv), the molar volume of saturated liquid (V^l), and the vapor pressure (P^sat). Determine B in cm³/mol for methyl ethyl ketone at 75^oC from the following data at this temperature:

ΔH^lv=31,600 J/mol, V^l = 96.49 cm³/mol

ln(P^sat)=48.157543-5622.7/T^_ 4.70504 ln(T) T(K), P^sat (kPa)

Interstellar gas in many galaxies is in virial equilibrium with the stars, in that the rms speed of the gas particles is the same as the rms stellar speed. Consider a large elliptical galaxy with a virial radius of 150 kpc and a mass of 5 × 1012 solar masses. Calculate the rms stellar velocity using the virial theorem. Hence estimate the temperature of the interstellar gas, assuming that it is composed entirely of hydrogen.
