В. В.
V V
RT
where S is entropy, V is volume, p is pressure, T is temperature, R is the ideal gas constant, Vm is
molar volume, B2 and B; are virial coefficients that depend on temperature T. Suppose B3 = 0, B2 =
-15.8x100 m moll and dB2/dt = 0.25x10 mmol K-, evaluate this expression for 1 mole of
argon in 25 cm at 303.15 K.​
