Science Notes-- Chapter Four, Pure Substances and Mixtures

I decided to post my science notes. Anyone can use them, as long as you mention the name, "Frege" in it.

Science—Chapter Four: Pure Substances and Mixtures:      /37

Yeah, so you guys can use these notes as well. The underlined parts are IMPORTANT parts, on which you will be marked on. It’s out of 37.

Defintions:         /32

Matter: Anything that takes up space, has mass, and is made up of particles.         /3

Properties: The characterisitics of materials. Every materiall has it’s own unique set of characteristics. Ex. Colour, odour, density.    /5

Mixture: A material made up of several different types if materials; in a mixture, each material retains its own properties.    /3

Heterogeneous: Made up of parts that retain their own properties that are not visable to the unaided eye.      /3

Homogeneous: of materials, having only on set of properties. Every part if the material is the same through out.   /2

Mechanical Mixture: A substance made up of more than one materials, in which they can easily be identified.    /2

Solution: A homogeneous mixture of two or more substances; the distinct properties of the different substances that make up a solution are combined into one set of properties.     /3

Pure Substance: A material that is composed of only one type of particles. Ex. Gold, oxygen, silver, copper, water, sugar, salt.    /8

Particle Theory of Matter---         /5

Defintion: A scientific model of the structure of matter.    /2

Points:

All matter is made up of extremely small particles.    /1

Each Pure Substance has its own kind of particles, different from the particles of other pure substances.    /2

Hope this helps!
