Physical Properties are what the substance shows visually or things you can feel on the substance. Examples of Physical Properties are the smooth edges of a rock, and if it is chipped by an outside force and gets sharp that is a physical change. A chemical reaction might be burning hydrogen ultimately changing it into oxygen. ]]> 2018-03-22 17:53:57 UTC https://padlet.com/21kthompson/ml2ly5i7frjx/wish/245152787 21kthompson https://padlet.com/21kthompson/ml2ly5i7frjx/wish/245156369
In a solid, these particles are packed closely together and are not free to move about within the substance. Molecular motion for the particles in a solid is confined to very small vibrations of the atoms around their fixed positions; therefore, solids have a fixed shape that is difficult to change. Solids also have a definite volume; that is, they keep their size no matter how you try to change them. Solids are divided into two main categories, crystalline solids and amorphous solids, based on how the particles are arranged. ]]> 2018-03-22 17:59:37 UTC https://padlet.com/21kthompson/ml2ly5i7frjx/wish/245156369 21kthompson https://padlet.com/21kthompson/ml2ly5i7frjx/wish/245161389 Gases have three properties. 1, they  can be compressed easy. 2, they fill up far more space than the liquids or solids from which they form. 3, they expand. They have a molecule structure that is not organized, and is spread out very far. ]]> 2018-03-22 18:07:15 UTC https://padlet.com/21kthompson/ml2ly5i7frjx/wish/245161389 21kthompson https://padlet.com/21kthompson/ml2ly5i7frjx/wish/245164403 Properties of liquids, they are almost in-compressible. liquids have no definite shape that they take form of unless you put them in some sort of item and chuck that in the freezer, but still that is not its own shape it is just stuck in the shape of whatever it is in. the structure in water is very close and tight. ]]> 2018-03-22 18:11:47 UTC https://padlet.com/21kthompson/ml2ly5i7frjx/wish/245164403 21kthompson https://padlet.com/21kthompson/ml2ly5i7frjx/wish/245166927 Plasma has different physical forms depending on the current, and or what item they are touching or going through. lighting is plasma, the sun has plasma. and the structure of plasma has + and - charged particles.
