Mix And Flow Of Matter

Front 1

Particle Theory of Matter

Back 1

-All matter is made of particles called atoms
-Atoms are always in motion
-Different substances are made up of different combinations of atoms
-Atoms cannot be created or destroyed, only changed from one form to another

Front 2

Mass

Back 2

is the amount of matter in a object

Front 3

Law of Conservation of Matter

Back 3

Atoms/Matter cannot be created or destroyed only changed from one form to another

Front 4

Density

Back 4

amount of atoms/ given amount of volume

Front 5

Viscosity

Back 5

is a fluids internal resistance or friction that keeps it from flowing. As the temperature increases in a liquid, the viscosity decreases.

Front 6

Melting

Back 6

when a solid for example water changes it form due to the change in temperature.

Front 7

Boiling

Back 7

it is the process when a substance reaches it boiling point thus a liquid turns into a gas.

Front 8

Solid

Back 8

has a definate shape

Front 9

Liquid

Back 9

does not have a definite shape, it takes the shape of their container.

Front 10

Condensation

Back 10

gas to liquid

Front 11

Solidification

Back 11

gas to solid

Front 12

Evaportaion

Back 12

liquid to a gas

Front 13

Matter

Back 13

is anything that has mass and takes up space

Front 14

Energy

Back 14

a supply or source of electrical, mechanical, or other form of power (If something isn't matter, it is energy).

Front 15

Physical change

Back 15

A physical change is reversible,For example, the freezing of water would be a physical change because it can be reversed

Front 16

Chemical change

Back 16

A chemical change irreversible,whereas the burning of wood is a chemical change - you can't 'unburn' it

Front 17

Pure substance

Back 17

is a made up of one kind of matter and has a unique characteristic or properties (example baking soda).

Front 18

Mixture

Back 18

is made up of a combination of different substances and each substance keeps it properties (which may be hard to identify).

Front 19

Homogeneous mixture

Back 19

is a mixture in which the different substances cannot be seen; a mixture that looks like all one substance.

Front 20

Heterogeneous mixture

Back 20

another name for mechanical mixture

Front 21

Mechanical mixture

Back 21

you can see the different substances that make up the mixture (example soil and mixed vegetables).

Front 22

Suspension

Back 22

: is a cloudy like mixture in droplets or a tiny pieces of a substance are held within another substance and if left undisturbed, its parts will usually separate out. Muddy water is an example of suspension.

Front 23

Colloid

Back 23

is also a cloudy like mixture in droplets or tiny pieces so small they do not separate easily (example: homogenized milk, Cool Whip, mayonnaise).

Front 24

Element

Back 24

are any of the four primary substances, earth, air, fire, and water, that were formerly thought to be the materials from which all matter is constructed.

Front 25

Compound

Back 25

something made by combining two or more things.

Front 26

Chromatography

Back 26

is a test used to determine if they are pure substances or solutions. Also it is the technique to discovering chemical components.

Front 27

Evaporation

Back 27

liquid to a gas

Front 28

Atom

Back 28

All matter is made of atoms no matter if the matter is biotic, dead or abiotic.

Front 29

Unsaturated solutions

Back 29

a solution in which more solute can dissolve.

Front 30

Saturated solution

Back 30

a solution in which no more solute can dissolve at a given temperature.

Front 31

Solubility

Back 31

the maxium amount of solute you can add to a fixed volume of solvent at a given temperature (this happens at a stauration point).

Front 32

Aqueous

Back 32

means dissolved in water

Front 33

Solute

Back 33

the substance being dissolved

Front 34

Solvent

Back 34

the substance doing the dissolving (usually water).

Front 35

Tyndall effect

Back 35

is the scattering of light by a colloidal particles or particles in suspension. (Named after John Tyndall).

Front 36

A fluid

Back 36

a substance that continually flows under shear stress. All liquids and all gases are fluids under the right circumstances.

Front 37

Archimedes Princple

Back 37

The strength of the buoyant force acting upward on a partially or fully submerged object is equal to the weight of the liquid displaced by that object.

Front 38

Buoyancy

Back 38

a term that describes how liquids exert and equal and opposite force on gravity, that pushes upward.

Front 39

Density

Back 39

amount of atoms/ given amount of volume

Front 40

Miscibility

Back 40

how well a fluid can dissolve other substances

Front 41

Compressibility

Back 41

how much a fluid will compress

Front 42

Compression

Back 42

something that squishes and absorbs force

Front 43

Pressure

Back 43

is a meaures of the force acting perendicular to a unit area.

Front 44

Weight

Back 44

your gravitational pull towards the earth
