In a certain polytropic process the volume of argon was increased 4 times. Simultaneously, the pressure decreased 8 times. The molar heat capacity of argon in this process, assuming the gas to be ideal, is
Options:
Answer:
A
Solution:
PVx = const gives 4x = 8, so x = 1.5. C = Cv + R/(1 - x) = 3/2R - 2R = -R/2 = -4.16 ≈ -4.2 J/K-mol. Matches (a).
