The Particle Theory. 1. The theory also states that the degree to which these particles move around depends on the amount of energy that is present in the matter and what the nature of the relationship is between the various particles. Each pure substance has its own kind of particle, different from the particles of other pure substances 3. 0000005334 00000 n Particles attract each other 4. Particles at a higher temperature move faster than particles at a lower temperature
