The equation of state of a gas Can be written in the form p = nkT(1 + Bn) where p is the mean pressure of the gas, T its absolute temperature, n = N/V the number of molecules per unit volume, and B2 = B(T) is the second virial coefficient. of the temperature. Find how the mean internal energy E of this gas dspends on its volume V, i.e., find an expression for (0E/0V)r. Is it positive or negative? The discussion of Sec. 5-10 showed that B, is an increasing function
