Formula Sheet — Kinetic Theory

Important formulas and equations from Kinetic Theory for CG PET Physics.

Formulas — Kinetic Theory

Molecular Nature and Gas Behavior

PV = μRT
PV = NkBT
P = (ρRT)/M0

Kinetic Theory and Molecular Speeds

P = (1/3)nmv̄²
PV = (2/3)N⟨KE⟩
⟨KE⟩ = (3/2)kBT
vrms = √(3RT/M0) = √(3kBT/m)
vmp = √(2RT/M0)

Degrees of Freedom and Equipartition

⟨E⟩ = (f/2)kBT
U = (f/2)NkBT = (f/2)RT

Specific Heat Capacities

CV = (f/2)R
CP = CV + R
γ = CP/CV = (f+2)/f
