Answer:

1 = An ideal gas steadily loses energy due to elastic collisions with the walls of  container

Explanation:

The first option is not an assumption of kinetic molecular theory because according KMT the collision of gas molecules with each other and wall of container is perfectly elastic. None of the energy is lost during these collisions.

While all other options are postulates of kinetic molecular theory.

1. The kinetic energy of gas molecules is only depend upon the temperature.

2. The gas molecules are randomly moves in any direction and thus colloid with each other and wall of container.

3. The volume of gas particles is negligible as compared to the volume of container.

4. The ideal gas does not exhibit attractive and repulsive forces.
