Science MATTER

Element

Pure substance that cannot be broken down into simpler substances and consists of only one type of atom.

compound

Substance formed when two or more elements chemically bond together in fixed proportions.

mixture

A combination of two or more substances that are not chemically bonded they are physically bonded and can be separated by physical means.

Heterogeneouse

A type of mixture in which the components are not uniformly(evenly) distributed, resulting in distinct regions or phases. Examples include salads or sandy water.

Homogeneous

A type of mixture in which the components are evenly distributed, resulting in a single phase. Examples include saltwater and air.

solute

Substance that gets dissolved

solvent

Substance that does the dissolving

Physical Property

characteristic you can observe without changing it

Chemical property

a characteristic of a substance that can only be measured or observed when it undergoes a chemical change to form an entirely different kind of matte

solubility

how well a substance can dissolve into a liquid

conductivity

how easily electricity or heat can travel through a material

Viscotsty

a measure of how thick a fluid is and how slowly or quickly it flows

mallebility

the ability of a material to be hammered, pressed, or rolled into flat sheets or new shapes without cracking or breaking

reactivity

how easily a substance changes or joins with other things to make something new.

pH

a special measuring tool that tells us how acidic or basic (also called alkaline) a liquid is (0-14)

Vaporization

liquid to gas

Evaporization

liquid to gas slowly

Sublimintation

when a solid turns directly into a gas without ever becoming a liquid first. [1]

deposition

gas to solid

Condensation

Gas cools down and turns into a liquid

Exothermic

heat goes out. deposition,condensation,freezing

endothermic

substance absorbs heat during melting,vaporization, and sublimation

Kinetick Energy

ebergy an object has when moving

Find density

D=m/v

FInd Volume

V=M/D

Find mass

M=D*V

element

a pure substance made of only one type of atom that cannot be broken down into simpler substances

compound

a pure substance made of two or more different elements chemically bonded together in a fixed proportio

mixture

a physical combination of two or more substances that are not chemically joined together. [1]
