Formula and explanation
Formula: P = (1)/(3) n m v² = (2)/(3) n k Applicable conditions: Ideal gas, large number of molecules, equilibrium state. Explanation: The pressure formula derived from kinetic theory. P is pressure, n is molecular number density, m is molecular mass, v² is the mean square speed, k = (1)/(2) m v² is the average translational kinetic energy per molecule.
