The Boyle temperature of a gas is defined to be the temperature at which the second virial coefficient in the inverse volume expansion vanishes. A certain gas obeys the equation of state RT a Р- Vm – b T³V - m where a and b are numerical constants. Expand the equation of state in virial form, and determine the Boyle temperature of the gas in terms of a, b and R.
