Which statement is part of 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

A. Gas particles are in constant motion.

Step-by-step explanation:

The first postulate of Kinetic Molecular Theory is that gas particles are in constant motion.

B is wrong. Kinetic Molecular Theory assumes that there are no attractive forces between the molecules.

C is wrong. Kinetic Molecular Theory assumes that collisions between molecules are elastic.

D is wrong. Kinetic Molecular Theory assumes that there are no attractive forces between the molecules of the gas and those of its container.
