Molecular kinetic theory model (AQA A-Level Physics): Flashcards

Random movement of particles due to molecular bombardment

Pressure inversely proportional to volume

Volume directly proportional to temperature

Pressure directly proportional to temperature

None - no attractive or repulsive forces between molecules

$pV = \frac{1}{3}Nm(c_{rms})^2$

Only kinetic energy (no potential energy)

$\frac{1}{2}m(c_{rms})^2 = \frac{3}{2}kT$

$k = 1.38 \times 10^{-23}$ J K$^{-1}$

Perfectly elastic - no kinetic energy lost
