Postulate 1: The particles of a gas are extremely small and have no mass.
This postulate means that the average mass of a gas particle is extremely small compared to the size of the entire gas. As a result, we can neglect the mass of individual particles when calculating the properties of the gas.
Postulate 2: The particles of a gas are in constant random motion.
This postulate states that particles in a gas are not bound to any specific location or direction. They are constantly moving in a random fashion, and their motion is independent of the motion of other particles.
Postulate 3: The particles of a gas are always separated from each other by a negligible distance.
This postulate means that the particles of a gas are extremely far apart from each other. This allows us to neglect the intermolecular forces between the particles, which would otherwise affect the properties of the gas.
Postulate 4: The average distance between particles in a gas is much greater than the size of the particles themselves.
This postulate means that the particles in a gas are widely spaced out, and their average distance is much greater than the size of the particles themselves. This allows us to neglect the effects of the kinetic energy of individual particles on the overall properties of the gas.
Postulate 5: The forces acting on a gas particle are only the forces of collision with other gas particles.
This postulate means that the forces of attraction between the particles are negligible compared to the forces of collision. This allows us to neglect the effects of these forces on the motion of the particles
