Passage / Comprehension
An ideal gas whose adiabatic exponent equals γ is expanded according to the law P = α V2, where α is a constant. The initial volume of the gas is equal to V0. As a result of expansion, the volume doubles.
What is the magnitude of work performed by the gas?
Options:
Answer:
C
Solution:
w = ∫ P dV = α∫V02V0V2 dV = (α)/3(8V03 - V03) = (7α V03)/3. Matches (c).
