Liquid and solid

The air we breathe is made up of different gases, but it is mostly nitrogen and oxygen. Gases A gas has neither a definite volume nor a definite shape. Gas The atoms and molecules in gases are much more spread out than in solids or liquids. Updated June 05, Matter occurs in four states: solids, liquids, gases, and plasma.

Solids A solid has a definite shape and volume because the molecules that make up the solid are packed closely together and move slowly.

definition of solid liquid and gas

Unlike regular plasma, degenerate plasma expands little when heated, because there are simply no momentum states left. We exhale water vapour whenever we breathe out.

state of matter

We can see through some solids like glass. When in a normal solid state, the atoms of matter align themselves in a grid pattern, so that the spin of any electron is the opposite of the spin of all electrons touching it.

Helmenstine holds a Ph. Here you see mercury in its common liquid form. Matter that feels hard and maintains a fixed shape is called a solid; matter that feels wet and maintains its volume but not its shape is called a liquid. In the rare equations that plasma is used in plasma is symbolized as p. This describes the liquid state. The anion and cation are not necessarily compatible and would demix otherwise, but electric charge attraction prevents them from separating. When in a normal solid state, the atoms of matter align themselves in a grid pattern, so that the spin of any electron is the opposite of the spin of all electrons touching it. Near absolute zero , a substance exists as a solid. Solids are sometimes formed when liquids or gases are cooled; ice is an example of a cooled liquid which has become solid. Under the right conditions, over half a dozen elements - including sodium and bismuth - are thought to be capable of existing in the newly discovered state, researchers say. Dropleton Main article: Dropleton A "quantum fog" of electrons and holes that flow around each other and even ripple like a liquid, rather than existing as discrete pairs. Some substances exist as gases at room temperature oxygen and carbon dioxide , while others, like water and mercury metal, exist as liquids. Quantum Hall state Main article: Quantum Hall effect A quantum Hall state gives rise to quantized Hall voltage measured in the direction perpendicular to the current flow. Solids may liquefy when they heat up; molten lava is an example of solid rock which has liquefied as a result of intense heat.

Their anions and cations appear to diffuse within compartmentalized layers or micelles instead of freely as in a uniform liquid. According to Einstein's theory of relativity, a high-energy nucleus appears length contracted, or compressed, along its direction of motion.
