The thermodynamic law, PVy = constant, is not applicable in case of______________?
Correct answer: A. Free expansion of an ideal gas
- A. Free expansion of an ideal gas
- B. Ideal compression of air
- C. Adiabatic expansion of steam in a turbine
- D. Adiabatic compression of a perfect gas
Explanation
The relation PVᵞ = constant describes a reversible adiabatic process for an ideal gas. Free expansion is irreversible and has no opposing pressure work, so this relation does not apply.
