Definitions (Matter)
|
Matter
|
Anything that has
mass and takes up space
|
Mass
|
A measure of the
amount of matter in an object
|
Density
|
The amount of matter
in a certain volume of a substance-found by dividing the mass by the volume
|
Volume
|
A measure of how
much space the matter of an object takes up
|
Weight
|
A measure of how
gravity pulls on an object
|
Property
|
Something that can
be observed about an object or a group of objects
|
Buoyancy
|
The upward push of a
liquid or gas on an object placed in it
|
State of matter
|
One of three common
forms that matter can take: Solid, liquid or gas
|
Surface tension
|
A property of
liquids where particles pull toward the other particles creating a
"skin" on the surface
|
Freezing- a liquid turns into a solid
Boiling- a liquid becomes a gas
Condensation- a gas becomes a liquid
Evaporation-liquid becoming a gas
Physical properties: | Properties that do not change the chemical nature of matter. Examples of physical properties are: color, smell, freezing point, boiling point, melting point |
Chemical properties: | Properties that do change the chemical nature of matter |
Qualitative observations- use your senses to observe the results. (Sight, smell, touch, taste and
hear.)
Quantitative observations- are made with instruments such as rulers, balances, graduated
cylinders, beakers, and thermometers. These results are measurable.
Atom- the basic building block for all matter in the universe. They are extremely small and are made up of a few even smaller particles. The basic particles that make up an atom are electrons, protons, and neutrons.
Law of Conservation of Matter- Mass or matter can not be created or destroyed.

Element- a pure substance that is made from a single type of atom. They are the building blocks for all the rest of the matter in the world. Examples of elements include iron, oxygen, hydrogen, gold, and helium.
