What Is Plasma

The video explores the four states of matter: solid, liquid, gas, and plasma. It explains the transitions between these states, focusing on how heat affects particles. Plasma, the fourth state, is formed when gas is heated to the point where electrons are stripped from atoms, creating free electrons and ions. Plasma can conduct electricity, unlike gases. Examples of plasma include lightning, stars, and neon signs. The video also covers the use of plasma in technology, such as fluorescent lights and plasma TVs.
