Final answer:
Plasma is the fourth state of matter and examples include stars, auroras, and a neon sign.
Step-by-step explanation:
Plasma is the fourth state of matter, and it is made up of charged particles. Examples of plasmas include stars, auroras, and a neon sign. In stars, the high temperature causes the atoms to lose their electrons, resulting in a plasma state. Auroras occur when charged particles from the Sun interact with the Earth's atmosphere, creating glowing lights. Neon signs are filled with a gas that, when electrified, creates a plasma that emits light.
