Plasma, the "fourth state," is characterized by lack of shape, and it cannot be classified as gas, liquid, or solid. Examples of plasma are plasma ball and the contents of a fluorescent bulb. The fifth state has already been discovered by scientists. It is called Bose-Einstein Condensate (BEC), but in Grade 3, the focus of study is only on the three states of matter: solids, liquids, and gases. Let us have some exercises on grouping of matter.
