of matter offers a description of the microscopic properties of atoms (or molecules) and their interactions, leading to observable macroscopic properties (such as pressure volume, temperature |
kinetic molecular theory |
|
|
An application of the theory is that it helps to explain why matter exists in different phases (solid liquid, and gas) and how matter can change from one phase to the next. |
kinetic molecular theory |
|
|
The kinetic molecular theory of matter states that |
1.Matter made up particles that are constantly moving. 2.All particles have energy, but the energy varies depending on temperature. 3.temperature of substance is measure of the average kinetic energy 4.change phase may occur when energy of particles is changed 5.There are spaces between particles of matter 6.attractive forces between atoms/molecules, and become stronger particles move closer together |
