#68. The volume of an ideal gas approaches zero as the temperature approaches
A. -273 K
B. -272 C
C. 0 C
D. 0 F
E. 212 F

The answer is B but I don't really understand why. I know ideal gases have no intermolecular forces/ volume but I thought as the temperature increases gases behave more ideally (volume approaching 0).

Charles's law states that volume is directly proportional to temperature. As the volume is approaching zero, the temperature must be approaching zero as well. -272C is approx 0K.
