Final answer:

The correct answer is D) All of the above, as gases consist of negligible volume particles in constant motion, and undergo elastic collisions, which are all postulates of the kinetic molecular theory of gases.

Step-by-step explanation:

The question asks which of the options listed are postulates of the kinetic molecular theory of gases. The correct answer is D) All of the above. The postulates of the kinetic molecular theory of gases are:

  • Gases consist of particles called molecules that are far apart from each other, making the volume of gas particles negligible compared to the volume of the gas itself.
  • The gas molecules are in constant motion, moving in straight lines in random directions until they collide with other molecules or the walls of their container.
  • When gas particles collide, these collisions are elastic, meaning there is no net loss of kinetic energy.

These postulates explain ideal gas behavior, including how gas pressure is exerted and how changes in temperature affect a gas.
