What is Plasma?

Plasma, often referred to as the fourth state of matter, is a hot, ionized gas composed of positively charged ions and free electrons. At high temperatures, such as those found in stars or lightning, matter can be converted into plasma. Unlike solids, liquids, and gases, plasma does not have a definite shape or volume and is electrically conductive. This unique state of matter plays a crucial role in various natural phenomena and technological applications, ranging from fusion energy to plasma TVs. Understanding plasma is essential for comprehending the fundamental building blocks of the universe.
