Step-by-step explanation
The molecular molecular theory of matter states that "matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state.
Therefore, the true statements of molecular kinetic theory of matter from the options are:
Only gas particles are constantly in motion.
The mobilty of particles is dependent on their energy
Matter is made up of particles
