Solids can also change directly into gases through the process of the sublimination, and gases can likewise change directly into solids through deposition.
What I learned: 
That the solid can be transformed into liquid and As a result, a solid has a stable.]]> 2018-09-06 12:36:04 UTC https://padlet.com/perlaupia0407/649b1dwofa97/wish/278375435 perlaupia0407 https://padlet.com/perlaupia0407/649b1dwofa97/wish/278389211 In phisics a state of matter is one of distinct forms in which matter can exict.
Historically, The distinction is made based on qualitative differences in properties.Matter in the solid state maintains a fixed volume and shape,with component particles -atoms-molecules or ions- close together a fixed into place.

The types of matter:
1- Solid
2- Liquid
3-Gas 
4- Plasma 
5- Phisical and Chemical Change ]]> 2018-09-06 12:59:45 UTC https://padlet.com/perlaupia0407/649b1dwofa97/wish/278389211 perlaupia0407 https://padlet.com/perlaupia0407/649b1dwofa97/wish/278398424 A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a nearly constant volume independent of pressure.
The volume is definite if the temperature and pressure are constant. When a solid heated above its melting point, its becomes liquids, given that the pressure is higher than the triple point of the substances.
What I learned:
The highest temperature at which a given liquid can exist is its critical temperature ]]> 2018-09-06 13:15:52 UTC https://padlet.com/perlaupia0407/649b1dwofa97/wish/278398424 perlaupia0407 https://padlet.com/perlaupia0407/649b1dwofa97/wish/278408018 A gas is a compressible fluid. Not only will a gas conform to the shape of its container but it also expand to fill the container. In a gas, the molescule have enough kinetic energy so that effect of intermolecular forces is small and the typical distance between neibouring molecules is much greater than the size.
What I learned:
At a temperature below its critical temperature, a gas is also called a vapor, and can be liquefied by comprenssion alone without cooking]]> 2018-09-06 13:31:30 UTC https://padlet.com/perlaupia0407/649b1dwofa97/wish/278408018 perlaupia0407 https://padlet.com/perlaupia0407/649b1dwofa97/wish/278670558 It is important to understand difference between Phisical and Chemical Change. Some changes are obvious, but there are some basic ideas you should know. Phisical Change change are usually about Phisical states of matter. Chemical Change happend on a molecular level when you have two or more molecules that interact.
What I learned:
When you step on a can and crush it, you haved forced a Phisical Change.
Chemical Change happen on a much smaller scale.]]> 2018-09-06 22:49:36 UTC https://padlet.com/perlaupia0407/649b1dwofa97/wish/278670558 perlaupia0407 https://padlet.com/perlaupia0407/649b1dwofa97/wish/278683092 Like a gas,plasma does not have definite shape or volume. Unlike gases, plasmas are eletrically conductive, produce magnetic fields an electric currents, and respond strongly to electromagnetic forces.
What I learned:
A gas is usually converted to a plasma in one of two ways.]]> 2018-09-07 00:10:28 UTC https://padlet.com/perlaupia0407/649b1dwofa97/wish/278683092
