What is State Of Matter?

Matter is a physical substance that occupies space and has mass. Matter can exist in four different states: solid, liquid, gas and plasma. Each state of matter has unique properties that are determined by the arrangement of the particles which make up the matter. The solid state of matter is characterized by its rigidity and lack of ability to flow or take on new shapes due to its particles being firmly held together by strong bonds. Solids have a definite volume, shape, and density because their particles are arranged in an orderly manner with little internal motion. Examples include rocks, glass, plastic, ice cubes etc. In contrast to solids, liquids possess some characteristics similar to those of solids but also differ from them in other ways. Liquids have no definite shape as they will assume the shape or container it is placed in but maintain a constant volume like solids do. This is because their particles are more spread out than solids giving them greater freedom to move around compared to solids allowing them to flow freely from one place to another without changing their form . Water is a prime example for this type of matter   it takes on whatever shape its container provides yet maintains an essentially fixed volume regardless if it’s poured into containers with different shapes and sizes such as cups or buckets.(This sentence should be re-written)Examples include water (liquid), oil (liquid) etc. Gases follow certain laws set forth by chemistry known as the ideal gas law which allows us predict how gases will behave depending on temperature change while still maintaining constant pressure under certain conditions called Boyle’s Law . Every gas particle experiences random motion at any given time so they never stay still unlike liquids or solids where they’ll stay put until acted upon externally; this makes gases able expand indefinitely when not restricted so there’s no limit on how much space they occupy making them extremely volatile substances even at low temperatures or pressures . Examples include air (gas), oxygen (gas) etc.. Finally we come across plasma which cannot be found naturally outside Earth atmosphere since it requires high temperatures over 10 000 Kelvins for formation due thermal excitation taking place between charged particles inside this state . Plasmas usually occur when atoms become ionized after losing electrons thus creating free moving ions & electrons throughout plasma medium causing electric conduction at very high rates leading various types interactions between electromagnetic fields & plasma generating light energy seen during natural phenomena like auroras borealis lighting up night skies around poles.
