Passage / Comprehension
Recent Communications with the inhabitants of Neptune have revealed that they have a Celsius type temperature scale, but based on the melting point (0°N) and boiling point (100°N) of their most common substance, hydrogen. Further communications have revealed that the Neptunians know about perfect gas behaviour and that they find in the limit of zero pressure, the value of PVm is 28 l - atm at 0°N and 40 l - atm at 100°N.
What is the value of the absolute zero of temperature on their temperature scale?
Options:
Answer:
C
Solution:
PVm varies linearly with t (°N): slope = (40-28)/100 = 0.12 l-atm per °N, so PVm = 28 + 0.12 t. Absolute zero is where PVm = 0: t = -28/0.12 = -233.33°N. Hence (c).
