    Plasma
In summary, there are two types of plasmas: a gas of ionized atoms and a gas of subatomic particles. The term "plasma" can be applied to both cases and there is no sharp distinction between the two. The sun is an example of a plasma made up of ionized hydrogen atoms, specifically protons.

The Attempt at a Solution



I think i understand what a plasma is, but are there different types of plasma that fall into different categories? From the question it suggests different types are formed in different ways. What are these categories and how are the plasmas formed?

there's two different type?

Just a thought ... how about a gas of ionized atoms, and a gas of subatomic particles? Is the word "plasma" applicable to both cases? Not a sharp distinction between the two -- when we say the sun is largely a bunch of ionized hydrogen we mean a heap of protons.
 

1. What is plasma?

Plasma is the fourth state of matter, following solid, liquid, and gas. It is a highly ionized gas composed of positively and negatively charged particles.

2. How many types of plasma are there?

There are three main types of plasma: thermal, non-thermal, and ultra-cold. Each type has different characteristics and is used for different purposes.

3. What is thermal plasma?

Thermal plasma is created by heating a gas to extremely high temperatures. It is used in industrial applications such as welding and plasma cutting.

4. What is non-thermal plasma?

Non-thermal plasma is created by applying an electric field to a gas at low temperatures. It is used in applications such as air and water purification, and in plasma televisions.

5. What is ultra-cold plasma?

Ultra-cold plasma is created by cooling a gas to extremely low temperatures. It is used in research and medical applications, such as creating artificial blood plasma and studying quantum physics.
