According to the kinetic molecular theory of matter, all matter is made of tiny . The particles are in constant . energy is the enerty of an object because of motion. The measure of the speed of the moving or vibrating particles is called .
There are three ordinary of matter: solid, liquid, and gas. Matter that has definite volume and shape is called a . If matter has definite volume, but no definite shape it is called a . When matter does not have a definite shape or volume it is a . A fourth state of matter, the state, is matter that exists at extremely high temperatures and consists of electrically charged particles. A fifth state of matter is called , which is a low-density gas of extremely low energy.
The phase change when a liquid becomes a gas is called vaporization or evaporation. The opposite phase change is . When a solid skips the liquid phase and turns directly into a gas, this is called . The opposite phase change is called .
