Physical Chemical
Physical changes are concerned withenergy and states of matter. Physicalchange does not produce a newsubstance. Changes of state(melting,freezing, vaporization, condensation,sublimation,)are physical changes.
EX:Crushing a can ,melting an ice cube,breaking a bottle, cutting paper, andcutting wood
Chemical change is any change thatresults in the formation of chemicalsubstances. Chemical change involvesmaking or breaking of bonds betweenatoms.
EX:Burning wood, burning paper,decaying animals, explosion offireworks ,and digestion of food.

A physical property is an aspectof matter that can be observedor measured without changingit. Are properties that do notchange the chemical nature ofmatter.
EX:Color,smell,freezing point,boiling point, and melting point.
Chemical property may only beobserved by changing thechemical identity of a substance.Are properties that do changethe chemical nature.
EX: heat of combustion, reactivitywith water, PH, andelectromotive force.

An element is a type of mattercomposed of atoms that all haveexactly the same positive charge ontheir nucli.All atoms of an elementhave the same atomic number. It iscomposed of identical atoms. Anelement is a substance that cannot bedecomposed into simpler substances.
EX:Iron,carbon,oxygen,sylcum,sileum.
A compound is a pure substancecomposed of two or moresubstances that are chemicallycombined. In a compound aparticle, is formed when atoms oftwo or more elements join together.
EX:Table salt,water,sugar,carbondixiode,and baking soda.
Is that a substance is pure and isonly made up of one particle.And it cannot be broken downusing physical process.
Where a mixture is made up ofmore than one type of particle.And a mixture could be brokendown using physical process.
Homogenous
Heterogeneous
A Homogeneous is when twosubstances mix evenly.
EX:Lemonade,salt and water,kool-aid,paint,and soda
A Heterogeneous iscomposed of differentsubstances.
EX:Salt water,cement,cottagecheeze,sald,m&m’s
SOLUBILITY is an ability of a substanceto dissolve. In the process of dissolving,the substance which is being dissolved iscalled a solute and the substance inwhich the solute is dissolved is called asolvent.Its when a solution mixes evenly.
solution
A solution is a mixture that appears to be a singlesubstance, but is composed of particles of two or moresubstances.
Solute-The substance that is dissolved.
EX:kool-aid
Solvent-The substance in which the solute is dissolved
EX:water
A periodic table is a table thatdemonstrates the different types of atoms.You use it to find an element that has anumber of certain type of an atom. One ofthe pattern in a periodic table is that they’resorted by states of matter and if they’remetal or non-metal.
Atoms are made up of tiny bits of electricity,which are called protons,neutrons,and electrons.Protons have a positive charge, Electrons have anegative charge, and Neutrons have a neutralcharge. Both protons and electrons are thenucleus of an atom. They are so small you cantsee them, except with an electron microscope.Some atoms have more protons, neutrons andelectrons and some have fewer. An atom behavesdifferently depending on how many protons anod electrons it has.
SOLID:
A solid is one of the three states of matter. It isresistance to changes of shape, or volume. Unlikea liquid, a solid object does not flow to take theshape of its container, nor does it expand to fillthe entire volume available to it like a gas does.The atoms in a solid are bounded to each other.Particles n a solid are tightly packed, which areusually in regular pattern. They also vibrate butgenerally do not move from place to placentaparticles also don’t flow easily.
EX: Ice, sand, wood, brick
LIQUID:
Liquids do not have a definite shape. Ittakes the shape of its container. Liquids canbe flow,poured,and spilled. Particles in aliquid are close together with no regulararrangment.They vibrate, move about, andslide past each other. They also flow easily.
EX:Syrup,rain,milk,water,honey,
GASES:
Gases do not keep their shape, they completelyfill the container that their in flow with. They donot have a definite shape or a definite volume.They also have no color. The particles in a gas arewell separated with no regular arrangment.Theyflow easily, they also vibrate and move easily at ahigh speed.
EX:Steam,helium,air,bubbles,
