The particles in a gas are spread out and bonce off each other. 

Common Examples: helium, nitrogen, Freon, carbon dioxide, water vapor, hydrogen.

The particles in a liquid are together, but are able to move around each other. 

Common examples: water, blood, wine, coffee and rubbing alcohol

The particles in solid are tightly packed and can only vibrate.

Common examples: wood, sand, ice, bricks and steel

The particles in plasma are very spread apart and move very fast.

Common examples:  Lightning, auroras, the upper atmosphere (the ionosphere), stars and the sun, the solar wind, interstellar gas clouds

Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others]]> 2017-03-17 13:19:33 UTC https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160783896 20hdornath https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784220 A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.  Some common chemical properties are heat of combustion, enthalpy of formation, toxicity, and flammability. ]]> 2017-03-17 13:20:30 UTC https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784220 20hdornath https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784285 substances that are made of only one type of atom or only one type of molecule]]> 2017-03-17 13:20:44 UTC https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784285 20hdornath https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784336 a substance made by mixing other substances together]]> 2017-03-17 13:20:53 UTC https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784336 20hdornath https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784413 substances that cannot be chemically inter-converted or broken down into simpler substances]]> 2017-03-17 13:21:06 UTC https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784413 20hdornath https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784437 made up or consisting of several parts or elements]]> 2017-03-17 13:21:11 UTC https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784437 20hdornath https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784561 The first part of this theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties. The third part says compounds are combinations of two or more different types of atoms.]]> 2017-03-17 13:21:33 UTC https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784561 20hdornath https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784630 the basic unit of a chemical element. An atom is made of a nucleus, protons, and neutrons]]> 2017-03-17 13:21:47 UTC https://padlet.com/20hdornath/rlbtmz37ro5f/wish/160784630 20hdornath https://padlet.com/20hdornath/rlbtmz37ro5f/wish/163700857 1. What is a mixture?
- a substance made by mixing other substances together
2. How are they classified? What determines which type of mixture a substance is?
- They are classified as heterogeneous or homogeneous. Heterogeneous mixtures have visible layers, and homogeneous mixtures have a uniform appearance. 
3. Give examples of each type?
- Heterogeneous-> pizza, rocks in the sand, banana splits.
  Homogeneous-> Milk, kool-aid, blood, glue, lotion.
4. How can all mixtures be separated?
- Through a filtration process.]]> 2017-03-30 13:39:32 UTC https://padlet.com/20hdornath/rlbtmz37ro5f/wish/163700857
