• Adiabatic process • Compressor • Internal combustion engine • Isentropic process • Isobaric process Web3.12. This equation is the condition that must be obeyed by an ideal gas in a quasi-static adiabatic process. For example, if an ideal gas makes a quasi-static adiabatic transition from a state with pressure and volume p 1 and V 1 to a state with p 2 and V 2, then it must be true that p 1 V 1 γ = p 2 V 2 γ. The adiabatic condition of Equation ...
