1. Acid
corrosive substance: a sour-tasting compound that releases hydrogen ions to form a solution with a pH of less than 7, reacts with a base to form a salt, and turns blue litmus red.

2. Atom The building blocks of matter.
Made up of protons, electrons, and neutrons.
smallest part of element: the smallest portion into which an element can be divided and still retain its properties, made up of a dense, positively charged nucleus surrounded by a system of electrons.

3. Base
a base is thought of as a substance which can accept protons or any chemical compound that yields hydroxide ions (OH-) in solution.
turn red litmus paper blue
feel slippery to the touch when in solution, taste bitter

4. Boiling
Point
temperature at which liquid boils: the temperature at which a heated liquid turns to gas, e.g. 100 or 212 for water at sea level

5. suspension of small particles: solution but do not settle out.
Colliod
suspension of small particles: 
a suspension of small particles dispersed in another substance
Particles are larger than in a
solution but do not settle out.

6. Combustibility
likely to catch fire: able or likely to catch fire and burn
reacting with oxygen to produce flame: able to react vigorously with oxygen to produce heat and light, seen as a flame
substance that catches fire easily:
a substance or material that is able or likely to catch fire and burn

7. Compound A molecule that has two or more different elements
bonded together.
Example: H and O = H2O

8. Element
Two or more atoms are joined together chemically. Elements can be different or the same.
Example: O + O = O2

9. Anything that has a mass and a
Matter
Anything that has a mass and a
volume.

10. Heterogeneous Parts do not combine completely or evenly.
Example: sand and water

11. Solid

12. The Kinetic Theory of Matter
The theory states that All matter is made of tiny constantly moving particles.

13. matter that determines
Temperature
A physical property of
matter that determines
how much heat energy
an object can contain.

14. Liquid

15. Archimedes's Principal
Buoyancy is the ability of a fluid to exert an upward force on an object immersed in it

16. Gases

17. Plasma Is a super heated gas of positive & negative particles
When the molecules are traveling so fast, they begin to break apart and electrons become stripped from their atoms.
This is called ionization
The fastest movement of particles & is the MOST common form in the universe!

18. Pressure is a force that can influence all states of matter!
Is caused by particles colliding with their environment or each other
It is measured in units
of Pascal (Pa): Equal to
1 newton per square meter

19. Takes place below the boiling point of the liquid
Evaporation
a process in which something is changed from a liquid to a vapor without its temperature reaching boiling point
Takes place below the boiling point of the liquid

20. Melting
Solid to Liquid
Requires energy to break the physical bonds holding the particles together, this energy is called heat of fusion

21. Takes place above the boiling point of the liquid
Vaporization
Liquid to Gas
Taking in Energy
Takes place above the boiling point of the liquid

22. Releases energy (heat of vaporization)
Condensation
Gas to Liquid
Releases energy (heat of vaporization)
the process by which a vapor loses heat and changes into a liquid

23. (freezing) Liquid to Solid Releases energy (heat of fusion)
Solidification
(freezing)
Liquid to Solid
Releases energy (heat of fusion)
the same amount of energy required to change from a solid to a liquid

24. Solid to Gas or Gas to Solid
Sublimation
Solid to Gas or Gas to Solid
A solid changes directly to a gas without going through the liquid state
A gas changes directly to a solid without going through the liquid state

25. Cohesion is the attraction between the same kind of particles

26. the attraction between different kinds of particles
Adhesion
the attraction between different kinds of particles

27. Example: sugar in water
Homogeneous
Uniform distribution.
Example: sugar in water

28. Each keeps its own properties
Mixture
No Chemical Change
Each keeps its own properties
Can be separated

29. Groups of molecules that are mixed in a completely even distribution.
Solution
Groups of molecules that are mixed in a completely even distribution.
A solute dissolved in a solvent.

30. The substance to be dissolved.
Solute
The substance to be dissolved.
Example: sugar

31. Water is a universal one.
Solvent
The one doing the dissolving.
Water is a universal one.

32. Suspension
Can see the particles with the naked eye and they will settle out over time.
Example:
Salad dressing
