Thermodynamic Principles & Governing Equations

• First Law of Thermodynamics: ΔQ = ΔU + W (Conservation of Energy) • Isothermal Process (T = const): ΔU = 0 ⟹ ΔQ = W = nRT ln(V_f / V_i) • Isobaric Process (P = const): W = P · ΔV ⟹ ΔQ = n C_p ΔT • Isochoric Process (V = const): W = 0 ⟹ ΔQ = ΔU = n C_v ΔT • Adiabatic Process (ΔQ = 0): W = -ΔU ⟹ PV^γ = const
