What is plasma???

Question

...tom science

Answer 1

Plasma is the fourth state of matter. Many places teach that there are three states of matter; solid, liquid and gas, but there are actually four. The fourth is plasma. To put it very simply, a plasma is an ionized gas, a gas into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species, ions and electrons, to coexist. The funny thing about that is, that as far as we know, plasmas are the most common state of matter in the universe. They are even common here on earth. A plasma is a gas that has been energized to the point that some of the electrons break free from, but travel with, their nucleus. Gases can become plasmas in several ways, but all include pumping the gas with energy. A spark in a gas will create a plasma. A hot gas passing through a big spark will turn the gas stream into a plasma that can be useful. Plasma torches like that are used in industry to cut metals. The biggest chunk of plasma you will see is that dear friend to all of us, the sun. The sun's enormous heat rips electrons off the hydrogen and helium molecules that make up the sun. Essentially, the sun, like most stars, is a great big ball of plasma.

Answer 2

In physics and chemistry, a plasma is typically an ionized gas, and is usually considered to be a distinct phase of matter in contrast to solids, liquids, and gases because of its unique properties. "Ionized" means that at least one electron has been dissociated from a proportion of the atoms or molecules. The free electric charges make the plasma electrically conductive so that it responds strongly to electromagnetic fields.

This fourth state of matter was first identified in a discharge tube (or Crookes tube), and so described by Sir William Crookes in 1879 (he called it "radiant matter")[1]. The nature of the Crookes tube "cathode ray" matter was subsequently identified by English physicist Sir J.J. Thomson in 1897[2], and dubbed "plasma" by Irving Langmuir in 1928 [3], perhaps because it reminded him of a blood plasma [4].

Answer 3

There are 3 states of matter. Gas, liquid, and solids. Then..according to some it's 4. Gas, liquid, solid and sometimes plasma.

Answer 4

Plasma is what they fill the television sets with to make it sharper and more clearer than regular tube sets. it is also a source of energy that can be focussed to become more effecient.

Answer 5

actually, we can make plasma. its a state of matter - along with liquid, gas, and solids. the sun, for instance is made of plasma. lightning, is plasma. it occurs when the temperature is so hot, that the matter loses its properties.

Answer 6

Ionized gas, I think.

check urself dude
its your homework

Answer 8

something that we can't make so far
