Which assumption is NOT a part of the Kinetic Model of Gases?

In the Kinetic Model of Gases, one of the fundamental assumptions is that gas molecules are point particles that do not exert forces on one another except during elastic collisions. This implies that interactions with the walls of the container do not involve any energy losses and do not affect the motion of the molecules outside of these brief collisions.

The assumption that molecules interact with walls might suggest a form of energy transfer or interaction that goes beyond these brief, elastic collisions, which is not considered in the ideal gas approximation represented by the Kinetic Model. Instead, the focus is on the molecules moving freely and independently, maintaining their kinetic energy during interactions.

The other assumptions highlight the nature of gas behavior: molecules moving in straight lines reflects their unimpeded travel until they collide, the size of the molecules being negligible means that they occupy much less volume than the overall volume of the gas, and random motion emphasizes that the direction of each molecule's velocity changes constantly due to collisions. These assumptions collectively help explain the macroscopic properties of gases, such as pressure and temperature, using the microscopic behavior of individual gas particles.
