Q1) What is plasma?

Plasma is the fourth state of matter, distinct from solid, liquid, and gas. It consists of ionized gas particles that have been heated to extremely high temperatures, causing them to break apart into charged particles such as ions and electrons. Plasma is often referred to as the "ionized gas" state because of this high level of energy.
