1. About 1.0 × 1019 molecules per cubic centimetre.
2. Dust that has a positive electric charge will be attracted to objects that have a negative electric charge, and vice versa.
3. The particles move rapidly in all directions and in constant random motion.
4. Gas particles are constantly colliding with each other and the walls of their container.
5. Gas particles are in constant motion, and any object in motion has kinetic energy (Ek).
KMT POSTULATE:
(1) The particles in a gas are in constant, random motion.
(2) The combined volume of the particles is negligible.
(3) The particles exert no forces on one another.
(4) Any collisions between the particles are completely elastic.
(5) The average kinetic energy of the particles is proportional to the temperature in kelvins.
