Consider the Adiabatic Process.
I. It is a process where no heat enters or leaves the system (ΔQ = 0).
II. The system must be enclosed in perfectly insulating walls.
III. The equation of state is PV^γ = constant.
IV. Work is done by the system at the expense of its internal energy, causing a fall in temperature during expansion.
V. The slope of an adiabatic curve on a P-V graph is steeper than that of an isothermal curve.
