States Of Matter

By: Rita Harkless


Definition: Is The State Of Matter In Which Materials Have A Definite Shape And A Definite Volume.

Detail: The Term Definite Means That The shape And Volume Of A Pencil Won't Change As You Move The Pencil From A Desk Drawer To A Pencil Case To A Backpack.

Detail: The Term Definite Doesn't Mean That The Shape Or Volume Can Never Change.

Detail: Changing The Container Doesn't Change The Shape Or Volume Of A Solid.

Example: The Arrangement Of Atoms In A Copper Wire

Example: You Can Change The Shape Of A Pencil By Sharpening It


Definition: The State Of Matter In Which A Material Has A Definite Volume But Not A Definite Shape.

Detail: A Liquid Always Have The Shape Of Its Container.

Detail: A Liquid Can Be Poured From One Container To Another

Detail: If Your Estimate Is Not Accurate, You will Run Out Of Space In The Glass Before You Run Out Of The Liquid In The Bottle.

Example: Mercury Exists As A Liquid At Room Temperature.

Example: At Room Temperature Water Is A Liquid


Definition: Gas Is The State Of Matter In which A Material Has Neither A Definite Shape Nor A Definite Volume.

Detail: A Gas Takes The Shape And Volume Of Its Container

Detail: Gas Is Less Denser Than Air

Detail: They Are Natural Gases To Such As Fuel for Heating Homes

Example: Air, Which Is A Mixture Of Gases

Example: Balloons Are Filled With Helium, Which IS A Colorless Gas That Is Less Dense Than Air.


Definition: A Fourth State Of Matter Distinct From Solid Or Liquid Or Gas Or Present In Stars And Fusion Reactors.

Detail: Plasma In the Stars And In The Space Between Them Makes Up Over 99.9% Of The Visible Universe And Most Of That Is Not Visible

Detail: Plasma Consists Of A Gas Heated To High Temperatures That The atoms Ionize

Detail: Plasma Contains A Significant Number Of Electrically Charged Particles.

Example: A Fluorescent Light. The Electricity Charges The Gas And Create Plasma Inside

Example: Lightening Is A Form Of Plasma

Bose Einstein Condensate

Definition: A State Of Matter Of A Dilute Gas Of Bosons Cooled To Temperature Very Close To absolute Zero

Detail: Cornell And Weiman Created The Condensate.

Detail: The Molecules Gets Denser Or Packed Closer Together

Detail: If Plasmas Are Super Hot The Atoms In A Bose Einstein Condensate Are Total Opposites.

Example: Atoms That Exist In Temperatures Close To Absolute Zero

Example: The Bose Einstein Condensation Shows The Phenomenon Of Superfluity And Superconductivity .
