PV Diagram Explorer

PV diagram: pressure (P) on y-axis vs volume (V) on x-axis. Represents thermodynamic processes graphically.

Each point: a specific state with P, V, T (and n) defined.

Each curve: a process. Slope and shape tell what kind of process.

Isothermal (PV = const): hyperbola.

Adiabatic (PV^γ = const): steeper than isothermal.

Isobaric: horizontal line.

Isochoric: vertical line.

Area under curve = work done by gas: W = ∫P·dV.

Cyclic process: closed loop on PV. Enclosed area = net work over cycle.
