In adiabatic process for ideal gas:
APV = constant
BPV^γ = constant
CPV² = constant
DTV = constant
Answer & Solution
Correct answer: B. PV^γ = constant
Adiabatic (Q = 0): PV^γ = constant. Also TV^(γ-1) = constant, T^γ P^(1-γ) = constant. Adiabatic compression heats gas (work done on gas all goes to U → T rises).
