    Fire Gas
In summary, the conversation discusses the different phases of matter, including solid, liquid, gas, and plasma. Plasma is described as a super heated state of matter, which can also exist in a cooler ionic gas state. It is also noted that plasma is not always hot, and can be produced by passing a current through a rarefied gas. The conversation also touches on the confusion between plasma and fire, with plasma being described as ionized gas and fire being a chemical reaction of matter.

THroughout school we learned there were 3 basic phases of matter. SOlid, liquid, and gas. THen there is fire which I haven't really tried to put into one. I'd assume it's gas or a 4th phase that came along in my high school years...plasma. It's very hot and the elctrons are still jumping from the atoms so it may be charged. These are the 2 qualitites of plasma.

Plasma as I reasom exists in 2 states. cooler ionic gas and super heated when it becomes another state of matter. The reason I say this is because ionized gas is sometimes called plasma. THis is the case with the high definition TVs called Plasma TVs. It confuse dme cause I was reasoning that there's no way a TV could hold hot material that's the composition ofThe SUn

Plasmas aren't necessarily hot -- passing a current through a rarefied gas will produce a plasma. This is how fluorescent and neon lights work. Both kinds of lights use plasma, but are not hot.

Fire is not really matter, what you see when you look at a fire is a chemical reaction of matter converting from a solid to a gas e.g. wood to carbon dioxide and the release of chemical (electromagnetic) energy converted to heat and light.

2Chroot I said Plasma is just ionized gas, not always hot.


2Tzemach Are you suggestiong fire is just matter transistioning from one state to another?
 

1. What is plasma and how is it different from the other three phases of matter?

Plasma is often referred to as the fourth phase of matter, alongside solid, liquid, and gas. It is a highly ionized gas consisting of positively and negatively charged particles. Unlike the other three phases, plasma does not have a fixed shape or volume and is considered to be the most energetic state of matter.

2. How is plasma created and where can it be found?

Plasma can be created by heating a gas to extremely high temperatures, causing the atoms to lose their electrons. This process is known as ionization. Plasma can be found in various forms in nature, such as in lightning, the sun's corona, and the Earth's ionosphere. It can also be created artificially for use in technologies like plasma TVs and fusion reactors.

3. What are some unique properties of plasma?

Plasma has several unique properties, including its ability to conduct electricity and respond to magnetic fields. It is also highly reactive and can be used to create chemical reactions. Additionally, plasma can reach extremely high temperatures, with some types reaching millions of degrees.

4. How is plasma used in everyday life?

Plasma is used in a variety of technologies that we encounter in our daily lives. Some examples include fluorescent lights, plasma televisions, and neon signs. It is also used in industrial processes such as welding and cutting, and in medical treatments like plasma sterilization.

5. What are some current areas of research surrounding plasma?

Scientists are constantly studying plasma to better understand its properties and potential applications. Some current areas of research include using plasma in medicine for cell regeneration and cancer treatment, developing more efficient plasma propulsion systems for spacecraft, and studying the role of plasma in the formation and evolution of stars and galaxies.
