Here's why:
* Ideal Gas Assumption: The concept of an ideal gas assumes that gas particles are point masses with no volume and no intermolecular forces (attraction or repulsion) between them.
* Collisions: The only interaction between gas particles in this ideal model is through collisions. During collisions, momentum and energy are exchanged, influencing the particles' motion.
* Random Motion: Between collisions, gas particles move randomly and independently.
In summary: The motion of a gas particle is essentially independent of other particles except during brief moments of collision.
