The second virial coefficient B of a gas depends on
Apressure only
Btemperature only (for a given gas)
Cvolume only
Dneither temperature nor the nature of the gas
Answer: B
Virial coefficients are functions of temperature alone for a given gas; they do not depend on pressure or volume, which appear explicitly in the series. Different gases have different B(T) curves.
