Ideal Gas Law

PV = nRT

R = 8314 J/mol⋅K

Thermodynamic Processes

Adiabatic process: Q = 0

Isobaric process: P = constant

Isochoric process: V = constant

Isothermal process: T = constant

Specific Heats

cv = specific heat at constant volume

cp = specific heat at constant pressure

γ = cp/cv


H = U + PV

ΔH = Q (isobaric process)


S = k ln Ω

Ω = number of microstates

Carnot Cycle

η = 1 - Tc/Th

Clausius-Clapeyron Equation

dP/dT = ΔHvap/(T⋅ΔVvap)

Stefan-Boltzmann Law

P = σ$T^4$

Wien's Displacement Law

λmax = b/T

These are just a few of the important formulas on Thermodynamics for JEE Main. It is important to practice using these formulas to solve problems so that you can use them confidently in the exam.
