Passage / Comprehension
One mole of an ideal gas whose adiabatic exponent equals γ undergoes a process in which the gas pressure relates to the temperature as p = aTα, where a and α are constants.
At what value of α will the heat capacity be negative?
Options:
Answer:
C
Solution:
C < 0 requires 1/(γ-1) + 1 - α < 0, i.e. α > 1 + 1/(γ-1) = (γ)/(γ-1). Matches (c).
