what is plasma?

Answer 1

A plasma is an ionized gas, which means that at least one electron has been ripped from it. It is actually the most common of the five phases of matter. Lightning is an example of plasma.

Answer 2

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 3

In physics, plasma is a state of matter. It is essentially an ionized gas. At sufficiently high energy levels, electrons are stripped from atoms in a gas. The plasma thus consists of positively charged ions and free electrons, which makes the plasma electrically conductive. Most of the matter in the universe is plasma, because stars consist almost entirely of plasma.

Answer 4

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"). The nature of the Crookes tube "cathode ray" matter was subsequently identified by English physicist Sir J.J. Thomson in 1897, and dubbed "plasma" by Irving Langmuir in 1928 , perhaps because it reminded him of a blood plasma . Langmuir wrote:

"Except near the electrodes, where there are sheaths containing very few electrons, the ionized gas contains ions and electrons in about equal numbers so that the resultant space charge is very small. We shall use the name plasma to describe this region containing balanced charges of ions and electrons."
Plasma typically takes the form of neutral gas-like clouds or charged ion beams, but may also include dust and grains (called dusty plasmas).They are typically formed by heating and ionizing a gas, stripping electrons away from atoms, thereby enabling the positive and negative charges to move freely.

Plasmas are the most common phase of matter. Some estimates suggest that up to 99% of the entire visible universe is plasma. Since the space between the stars is filled with a plasma, albeit a very sparse one (see interstellar medium and intergalactic space), essentially the entire volume of the universe is plasma (see astrophysical plasmas). In the solar system, the planet Jupiter accounts for most of the non-plasma, only about 0.1% of the mass and 10^(−15)% of the volume within the orbit of Pluto. Notable plasma physicist Hannes Alfvén also noted that due to their electric charge, very small grains also behave as ions and form part of plasma (see dusty plasmas).

Answer 5

A plasma in chemistry and physics is an ionised gas produced usually bu induction,
it is called the fourth state of matter,
we can produce it by allowing a gas to flow in the middle of a strong magnetic field, the temperature of hot plasmas can reach 12000 degrees Centigrade

What is a Plasma Display Panel and How Does it Work?

Plasma technology is very different from that used in other display systems. The basic technology principal comprises of two sheets of etched glass sandwiched together creating thousands of tiny pockets each filled with gas and primary coloured Red Green & Blue phosphor, each of these tiny pin sized pockets is called a Pixel. Charged electrodes within each pixel react with the inert gas creating a state of plasma. This process results in the production of UV light, which in turn reacts with red, green and blue phosphor in each pixel to emit one of 16 million different colours and 256 shades of grayscale (black through to white).

Unlike traditional displays, where the image is scanned across the screen, the plasma pixels are all "lit" at once eliminating the effect of scan flicker. Having no electron beam, back-lighting or light polarization, the image is inherently sharper, brighter and perfect from edge to edge, the depth of the screen is approximately one tenth of a conventional tube device. Our new 503 and 433 screens feature enhanced picture performance.

This fourth state of matter

Answer 8

the name for the fluid your blood is made of - it is actually 'straw coloured' yellow in colour, and the red haemoglobin cells give it the red appearance.

Answer 9

the fourth state of matter. it is known to be present in our sun.

Answer 10

It is the non cellular portion of blood.
