The van der Waals' equation for one mole may be expressed as `V_(M)^(3)-(b+(RT)/(P))V_(m)^(2)+(aV_(m))/(P)-(ab)/(P)=0` where `V_(m)` is the molar volume of the gas. Which of the followning is incorrect?
A
For a temperature less than `T_(C),V` has three real roots
B
For a temperature less than `T_(C),V` has three imaginary roots
C
For a temperature equal to `T_(C)` all three roots of V are real and identical
D
On increasing the temp. `(TltT_(C))`, the three roots become closer to one another
Text Solution
Verified by Experts
The correct Answer is:
b
(b) Below critical temperature a gas can be liquified. So `V_(m)` has three real roots and identical.
