Acritical temperature
BBoyle's temperature
Correct Answer
Cboiling point
Dnone of these

Solution

The temperature at which the second virial coefficient of a real gas is zero is called Boyle's temperature.

It is the temperature at which a real gas obeys Boyle's law.

It is given by the expression $$T_B = \cfrac {a}{bR}$$ where a and b are the van der Waal's constants.

Boyle's temperature of a gas is always higher than its critical temperature.

Hence, the correct answer is option $$\text{B}$$.
