Formulas
2. Gas Laws and Equation of State
PV = KT
P1V1/(N1T1) = P2V2/(N2T2) = constant = k_B
PV = μRT
μ = M/M0 = N/N_A
PV = k_BNT or P = k_BnT
3. Kinetic Theory of Ideal Gas
P = (1/3) n m v̄²
E = (3/2) k_BNT ; (1/2) mv̄² = (3/2) k_BT
PV = (2/3)E
v_rms = (v̄²)^(1/2) = √(3k_BT/m)
4. Law of Equipartition of Energy
Each mode has average energy = (1/2) k_B T
For vibration: 2 × (1/2) k_B T = k_B T
