The kinetic particle theory explains the properties of the different states of matter. %PDF-1.3 %���� 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. 1. 0000006811 00000 n 0000001815 00000 n The transfer of energy from the particles of a warmer object to the particles of a cooler object. 0000004632 00000 n ���ɰ�O$� 7��!.s�sy/��e��xrTp�q�b��|�K�t 0000004739 00000 n A theory that explains what matter is made of and how it behaves. 0000006488 00000 n Each pure substance has its own kind of particle, different from the particles of other pure substances 3.
