Glass is classified as this type of matter
What is transparent (p 44)
A pure substance that cannot be broken down into a simpler substance and contains only one type of atom

When parts of a mixture are noticeably different from one another the mixture is classified as
What is heterogeneous (p 48)
When particles and gases and liquids spread out in a natural motion, moving from an area of higher concentration to an area of lower concentration.
What is a diffusion (p 54)
What are the two chemical properties we study?

Matter that you can not see through is classified as
Opaque matter (p 44)
A pure substance that contains two or more elements chemically joined in a fixed proportion
What is a compound (p 46)
When a mixture appears to contain only one type of substance because the substances are so evenly distributed that it is hard to distinguish one substance from another it is called... Example Sweet Tea
What is homogeneous (p 48)
The ability of a substance to allow heat to flow through it is called
What is conductivity (p 57)
What is a reversible physical change that occurs when a substance changes from one state of matter to another?
What is a phase change (p 67)
If you have two balloons that are the same size, therefore taking up the same amount of space but one if filled with water and one if filled with air. What can be said about the volume and mass of each balloon?
The balloons have the same volume but different masses. (p 45)
What is the smallest unit of a chemical compound, composed of two or more atoms bonded together
