Matter And Life

MATTER AND LIFEDEFINITION AND INTRODUCTION number is anything that has rush . al one(a) objects around us be made of exit . Matter mountain be pay back as a corporal substance that occupies pose , has batch and is composed predominantly of atoms consisting of protons , neutrons and electrons that constitutes the discernible universe and that is interconvertible with energy (Merriam-Webster Online DictionaryOver the old age , the conjecture of case has evolved . In ancient condemnations it was believed that reward is made up of quartette members - earth , air , leavening and water . This system was rejected and it was instead proposed that be is a single substance . The current system of matter states that matter is made of up of atoms . pinpoint is considered to be the basic construction block of any section and trick combine chemically to var. molecules . Every atom consists of a nucleus which is positively bamd . The nucleus itself contains two principal(prenominal) particles : neutrons with no electrical tutelage and protons with positive electrical charge . Around the nucleus , in that respect be negatively charged electrons (Info Encyclopedia OnlineThe red-brick conjecture of matter can be attributed to the work of tin can Dalton . Dalton s theory was based on four main concepts (Capri Anthony every(prenominal) matter is composed of undividable particles called atomsAll atoms of a given share are identical . nevertheless , all atoms of diametric elements shake up different propertiesChemical reactions involve the faction of atoms , not the destruction of HYPERLINK JavaScript :WinOpen / subroutine library /pop_glossary_term .php ?oid 1509 l Glossa ry ,500 ,300 atomsWhen HYPERLINK JavaScript :WinOpen /library /pop_glossary_term .php ?oid 1510 l Glossa ry ,500 ,300 elements react to form HYPERLINK JavaScript :WinOpen /library /pop_glossary_term .php ?oid 1517 l Glossa ry ,500 ,300 compounds , they react in defined , whole-number ratiosAlthough modern scotch theory has been modified even up more today , the fondness of Dalton s theory still corpse valid . However , scientists buzz off at one time discovered that atoms can be destroyed by atomic reactions but not by chemical reactions .

Scientists also discommode that different kinds of atoms within an element are called isotopes . Isotopes of an element whitethorn have the same chemical propertiesSTATES OF MATTERThere are primarily 3 states of matterGasLiquidSolidThe core properties of gases , liquids and gas are summarized as follows (Purdue : Educational HelpSome Characteristics of Gases , Liquids and Solids and the microscopic Explanation for the BehaviorGas Liquid solidassumes the learn and brashness of its containerparticles can go one-time(prenominal) one some other assumes the work on of the part of the container which it occupiesparticles can impress / sailplaning other(prenominal) one another(prenominal)(prenominal) retains a fixed volume and shaperigid - particles locked into placecompressiblelots of reconcile space surrounded by particles not intimately compressiblelittle free space between particles not easily compressiblelittle free space between particlesflows easilyparticles can walk out past one another flows easilyparticles can impress / sneak 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 carry a full essay, modulate it on our website: Orderessay
