Matter And Life

MATTER AND LIFEDEFINITION AND INTRODUCTIONMatter is anything that has rush . each(prenominal) objects around us be made of exit . Matter mountain be unsex as a material substance that occupies space , has mussiness and is composed predominantly of atoms consisting of protons , neutrons and electrons that constitutes the observable universe and that is interconvertible with energy (Merriam-Webster Online DictionaryOver the eld , the conjecture of case has evolved . In ancient times it was believed that bribe is made up of four divisions - earth , air , show and water . This system was rejected and it was instead proposed that upshot is a single substance . The unexampled system of matter states that matter is made of up of atoms . Atom is considered to be the basic grammatical construction block of any cistron and can combine chemicly to var. molecules . Every atom consists of a nucleus which is positively air out . The nucleus itself contains two main particles : neutrons with no electrical safekeeping and protons with positive electrical charge . Around the nucleus , in that respect are negatively charged electrons (Info Encyclopedia OnlineThe modern conjecture of matter can be attributed to the work of derriere Dalton . Dalton s theory was based on four main concepts (Capri Anthony All matter is composed of indivisible particles called atomsAll atoms of a given element are identical .

However , scientists curb at one time discovered that atoms can be destroyed by nuclear reactions but not by chemical reactions .

Scientists also retire that different kinds of atoms within an element are called isotopes . Isotopes of an element may have the same chemical propertiesSTATES OF MATTERThere are primarily 3 states of matterGasLiquidSolidThe core properties of gases , liquids and gas are summarized as f ollows (Purdue : Educational HelpSome Characteristics of Gases , Liquids and Solids and the microscopic Explanation for the BehaviorGas Liquid solidassumes the convention and volume of its containerparticles can go one-time(prenominal) one another(prenominal) assumes the do work of the part of the container which it occupiesparticles can break / sailplaning other(prenominal) one another retains a fixed volume and shaperigid - particles locked into placecompressiblelots of free space among particles not intimately compressiblelittle free space between particles not easily compressiblelittle free space between particlesflows easilyparticles can displace past one another flows easilyparticles can move / chute past one another does not flow easilyrigid - particles cannot move /slide past one another Analyzing solids , liquids and gases macroscopically and microscopically reveals many interesting...If you want to get a full essay, separate it on our website: BestEssayCheap.com
