Which statement is part of the kinetic molecular theory? A. Gas particles are in constant motion. B. Gas particles attract each other. C. Gas particles lose their energy during collisions. D. Gas particles stick to the walls of their container.

The answer to your question is: letter A

Explanation:

A. Gas particles are in constant motion. This statement is true because this theory says that Gases are composed of a large number of particles that behave like hard, spherical objects in a state of constant, random motion.

B. Gas particles attract each other. This statement is false because this theory says that there is no force of attraction between gas particles or between the particles and the walls of the container.

C. Gas particles lose their energy during collisions. This statement is false, this theory says that none of the energy of a gas particle is lost when it collides with another particle or with the walls of the container.

D. Gas particles stick to the walls of their container. This statement is false, the theory says that there is no force of attraction between gas particles or between the particles and the walls of the container.
