Pa·m³ = J
The equation of state relating pressure, volume, temperature, and quantity of an ideal gas composed of non-interacting point particles.
P V = n R T = N kB T
Intensive vs Extensive Properties
Thermodynamics & Statistical Physics
Various
Classification of thermodynamic properties based on whether they depend on system size or amount of matter.
Extensive: U, V, S, m, H; Intensive: T, P, ρ, μ
Internal Energy
Thermodynamics & Statistical Physics
J
The total microscopic energy contained within a thermodynamic system, comprising kinetic energies of particle translational/rotational/vibrational motion and potential energies of intermolecular forces.
U = (f/2) n R T (for ideal gas)
Isobaric Process
Thermodynamics & Statistical Physics
J
A thermodynamic change in state occurring under constant pressure conditions.
ΔP = 0, W = P ΔV, Q = ΔH = n Cp ΔT
Isochoric Process
Thermodynamics & Statistical Physics
J
A thermodynamic process occurring at constant volume, during which no mechanical boundary work is performed.
ΔV = 0 ⇒ W = 0, Q = ΔU = n Cv ΔT
Isothermal Process
Thermodynamics & Statistical Physics
J
A thermodynamic change in state occurring at a constant temperature throughout the system.
ΔT = 0 ⇒ ΔU = 0, Q = W = n R T ln(V2/V1)
