To understand how a plasma could be formed, imagine taking an ice cube, which is a solid (1'st state of matter), heating it until it melts and becomes a liquid (2'nd state of matter), heating it some more such that it forms steam, which is a gas (3'rd state of matter), and finally you keep heating it even more until the gas becomes ionized and forms a plasma (4'th state of matter).
