The physical properties of matter are quantifiable and observable traits of the material that can be measured, without changing the composition of the matter. Appearance, texture, color and odor are examples of matter ph... More »

The most common state of matter is plasma. Plasma makes up approximately 99 percent of visible matter in the universe, as well as most of what is invisible. More »

A phase change, also known as a phase transition, is a transformation in the physical state of a certain sample of matter. The phrase is most commonly used to describe the transition of a material between solid, liquid, ... More »
