Recent communications with the inhabitants of Planet X have revealed that they have a Celsius type temperature scale, but based on the freezing point (0°X) and boiling point (100°X) of their most common substance, methane. They know about perfect gas behaviour and find in the limit of zero pressure that PVₘ is 30 l - atm at 0°X and 45 l - atm at 100°X.
What is the value of the absolute zero of temperature on their temperature scale?
Options:
Answer:
A
Solution:
PVₘ = 30 + 0.15·t on their scale, since slope = (45-30)/100 = 0.15. Absolute zero: PVₘ = 0 ⇒ t = -30/0.15 = -200°X. Hence (a).
