Understanding Plasma: The Fourth State of Matter

The video explores plasma, a state of matter that makes up 99.9% of the universe. It explains how plasma is formed from gases at high temperatures, where electrons are freed from atoms, creating a mix of charged particles. Plasma behaves uniquely under electric and magnetic fields, generating light, as seen in phenomena like the Aurora Borealis. The video also discusses practical applications of plasma, such as in plasma TVs and healthcare, where it can destroy pathogens. Future uses of plasma include waste management and clean energy solutions.
