Science says matter is one of three forms, Liquid Solid or a Gas. What is Fire?

Fire is not matter. The combustible material is a 'solid' like  wood, but can be a 'liquid' like gasoline. The wood combusts, releasing 'gases' such as Carbon Monoxide and solids such as ash particulates. The "fire" is the energy released in the form of heat and light. That's my simple explanation.

Heat is absorbed by the particles of the substance causing their motion to increase.  As the motion of the particles increases they are able to break the forces of attraction holding them together and the move further apart.  So solids lose their regular pattern and become liquids; liquids break their attractions holding them together as a liquid and the particles move very far apart and become gases

the three properties of earth science are gas, liquid, and, solid. wind (or air moving quickly) is a gas.

Generally, heat makes substances get bigger. If you heat a solid up enough it will expand into a liquid. Gasses take up even more room. Water is a strange example where the solid form takes up less room than the liquid. So it does not follow the rule.

Fire is basically a mixture of hot gases.\nHence it's state can be taken as gaseous.\nI thinks "fire" in your question means flame.\nIf flame is very hot, then gases nearby get ionized and we get plasma- another state of matter

Fire is supposed to be a plasma and/or energy. It goes up because the expanded gasses in the flame "weigh" less than cool air (like a hot air baloon). It doesnt have a shape. it adapts to the shape of the container. It looks like a drop because of the hot air "pulling" it up.

Solid or gaseous, depending on what the question means when refering to non-metals:  There are 11 gases total out of the entire table (6 are nobel gases) and only 2 liquids..mercury and bromine.  The true non-metals comprise only 7 elements, and only 3 of those (hydrogen, nitrogen, and oxygen) are gases.  If you takea  looser definition of non-metals, which includes the true nonmetals plus the halogens and noble gases, the the answer is gaseous.  From the wording of the question, I would think they were trying to get you to say gaseous.

A real gas is a form of matter that will conform to the sides of its container.  As it is compressed its temperature increases.  It is the only form of matter than can be compressed at all.  Gas is the least organized form of matter.

Gases disperse to fill whatever container they occupy.   Gases are composed of matter and thus occupy space.  Since no two objects of matter can occupy the same space at the same time and a gas expands to occupy a given space a force(pressure) exist.  As the temperature increases the pressure increases because you are adding energy to the system.

The answer is glass... glass is an amorphus solid, meaning that it has solid characteristics, but is technically "flowing"

Solids, liquids, and gases refer to the individual properties of matter.  Air pollution is a mix of liquids solids and gases depending on what the pollution is.  Smoke for instance is just micro-solid particles in the air.  Hydrogen sulfide for example would be a gas.

Fire is the result of a combustion chemical reaction in which a hydrocarbon (a compound containing carbon and hydrogen) is reacted with oxygen forming carbon dioxide and water.  This reaction releases a lot of energy in the form of thermal (heat) radiation which is the result of fire.\n\nNote that there are other compounds which react with oxygen to release much energy and form oxides, but they're not relevant with respect to water.\n\nIce is water and not a hydrocarbon so it can not catch on fire.

u see,when a solid is heated to a certain extent it melts into liquid,and further heated it becomes a vapour,when it is heated to a greater extent,the molecules break up into atoms and atoms into very minute states.these form a cloud of particles which is called plasma.\n          for ex.,the temp. of stars is upto millions of degrees hence the plasma is present and also known as fourth state of matter.\n        i hope u got it!!!

you bet.  the old "solid, liquid, gas" classification is about as accurate as saying "animal, vegetable or mineral".  many substances DO fit into these categories, but these days there are a lot of forms of matter that do not fit neatly into any of them.\n\nthere are multiple types of solids:\n-crystalline solids\n-polycrystalline solids\n-amorphous solids\n\nmultiple types of liquids:\n-plain ol' regular liquids\n-solutions\n-superfluids\n\nmultiple types of gases:\n-plain ol' regular gases\n-plasma (ionized gas)\n\nand there are a lot of unusual forms of matter that don't fall neatly into these categories:\n-colloids (suspensions of particles in a fluid)\n-gels\n-quantum condensates (bose-einstein or fermionic condensates)\n-supersolids\n-some exotic ones found in high-energy and astro- physics, like neutron condensates, quark-gluon plasma, degenerate matter and strange matter\n\nthere are also some other types of thermodynamic phases:\n-the various kinds of magnetism (ferromagnetism, ferrimagnetism, antiferromagnetism, paramagnetism) are considered thermodynamic phases\n-when a material becomes superconducting it involves a phase transition of the electrons in the material\n\nand certainly there are others.  all of this depends on how you define a "form of matter."\n\nwikipedia has a list, though it is not complete:\nhttp://en.wikipedia.org/wiki/Phases_of_matter\n\ncheers

it is a state of matter because there is no other form like it that can be describe to be like that of plasma... it os found to be unlike solid liquid or gas...

Water. As a liquid it sculpts the landscape, sustains life, and dissolves most other substances. As a solid, it expands to a state less dense than as a liquid, can support immense amounts of pressure (trucks above the Arctic Circle drive on ice roads), and can rip through steel hulled ships. As a gas, it provides a remarkable stable compound of the volatile Hydrogen and combustible Oxygen which allows it to drive out weather system. \nAlso, water acts as both an ionic and molecular compound, as if that weren't enough already.
