1.
Matter
2.

3.
Propertv
- The ability to cause change or do work.
- Characteristic.

Property - Characteristics of ,matter that can be
measured and observed without changing the make-up of
the substance.
5. Chemical Propertv - Characteristics that show how a
particular substance will react under given conditions.
6.
State of Matter - Matter exists in one of four states....solid,
liquid, gas and plasma.
7.
Solid - State of matter that has a definite shape and a
definite volume.
8. Liquid -
State of matter that has a definite volume, but no
definite shape. A liquid takes on the shape of its container.
9. ges-- State of matter with no definite shape and no
definite volume.
10. Plasma -- State of matter that is a hot
ga-s
of electrically charged particles.
11. Phase Change - When matter changes
from one state to another.
12. Meltinq - When a solid changes to a liquid.
13. Freezinq - When a liquid changes to a solid.
14. V3porization
heated.
- When a liquid changes to a gas when
15. Evaporation -when a liquid changes to a gas under normal
temperatures.
16. condensation -when a gas changes to a liquid when it is
cooled
17. Meltinq Point
a liquid.
- The temperature
at which a solid changes to
18. Freezinq Point - The temperature at which a liquid changes
to a solid.
19. Densitv - The mount of mass per unit of volume of a
substance. This means how closely the mass of a substance is
packed into a given area or volume.
20. Atom
- The smallest particle of the element that still has the
properties of that element.
21, Element - A substance that cannot be made into simprer
substances by ordinary means.
22. Compound - When two or more elements combine
chemically. That means they cannot be separated by ordinary
means.
23. Mixture -- A combination of two or more kinds of matter
that
by ordinary means.
"li-6I=eparated
24. Heteroqeneous Mixture
from point to point.
- A mixture
25. Homogeneous Mixture
same throughout.
- A mixture whose makeup is the
whose makeup differs
Ex. Coffee
26. colloid - A heterogeneous mixture whose properties are in
between those of a solution and a suspension. Ex. Jello
27. Suspension - A heterogeneous mixture whose particles are
temporarily mixed in a liquid. Ex. Anything that says 'oshake
well".
28. Solution - A homogeneous mixture of two or more
substances. Ex. Soft drinks.
29. Solubilitv - The amount of solute that will dissolve in a given
amount of solvent.
30. Saturated - A solution in whick all of the solute ht the
solution can hold at a given temperature has been dissolved.
31. Unsaturated - A solution in which more solute can be
dissolved.
32. Supersaturated - A solution that has more solute dissolved
than is normal because it as been heated.
33. Boilinq Point Elevation - lncreasing the boiling point of
water by adding a solute. The water has to get hotter to boil with
the added solute. Ex. Salt in water.
34. Freezing Point Depression - Decreasing the freezing point
of water by adding a solute. The water has to get colder to freeze
with the added solute. Ex. Adding salt to the highways to keep
snow and rain from freezing on the roads.
35. Viscositv
- Thick, sticky
36. Malleabilitv -- capable of being extended or shaped by
hammering or by pressure from rollers.
37. Ductile -- ble to undergo change of form without breaking.
38. Conductivitv -- the property or power of conductinq heat,
electricity, or sound. (Conduct in this sense means to allow
something such as energy to pass freely.)
39, Reactivifu - The relative capacity of an atom or molecule to
undergo a chemical reaction (change) with another atom,
molecule, or compound.
40. Flammabilitv - Will burn
41. Precipitate -- To separate (a substance) in solid form from
solution.
a
42. Heat of Fusion - The amount of energy or heat required to
change a solid to a liquid.
43. Heat of Vaporization - The amount of energy or heat
required to change a liquid to a gas.
44. Exothermic
- Gives off heat in a chemical reaction
45. Endothermic
- Heat is absorbed in a chemical reaction.
46. Sublimation - Changes directly from a solid to a gas without
going through the liquid phase.
47. Deposition
48. Volume
occupies.
-
- Process of being deposited.
L x W x H, The amount of space something
49. Mass - The amount of stuff of which something consists.
50. Particle Motion
-
Matter is made of particles that are in
constant motion because of the movement of atoms.
51. Law of Conservation of Matter
-
Everything is made of
matter and cannot be created or destroyed.
52. Particle Theorv of Matter - Everything is made up of tiny
particles of matter that is always in constant motion because of
the movement of atoms.
