Formula Sheet — Thermodynamics

Important formulas and equations from Thermodynamics for CUET (UG) Physics.

Formulas — Thermodynamics

Fundamental Concepts and Laws

ΔQ = ΔU + ΔW
C = Q/(mΔT)
Cp - Cv = R

Thermodynamic Processes

W = μRT ln(Vf/Vi) = μRT ln(Pi/Pf)
W = μR(Ti - Tf)/(γ-1)
W = P(Vf - Vi) = μR(Tf - Ti)
PVγ = constant

Heat Engines and Second Law

η = 1 - T2/T1
η = W/Q1 = (Q1 - Q2)/Q1
COP = Q2/W = T2/(T1 - T2)

Special Cases and Applications

PVx = constant
C = Cv - R/(x-1)
