T WHAT IS MATTER? Matter is anything that takes up space, has mass and is made of atoms Mass- the amount of matter in an object MASS

Mass is measured by grams A kilogram = 1000 grams ATOM The basic unit of matter and the building blocks of things. Too small to be seen by the naked eye and requires a

microscope to view atoms ATOM An atom is made of protons, neutrons and electrons. The nucleus is the middle of the atom and is made of protons and neutrons The rings around the atom are the electrons

ELEMENT An atom that has a certain amount of protons. Example Hydrogen is an atom that has one proton Helium is an atom that has two protons PERIODIC TABLE OF THE ELEMENTS

A diagram showing all the elements known to man in order of the protons. MOLECULE A group of atoms held together by bonds Example: Water (H2O Two Hydrogen + 1 Water) Compound - A molecule

with two more more elements Question 1 Name the three things that makes up an atom.

Question 2 Is Oxygen Air ( O2 ) a compound? Question 3 What element has 5

protons? STATES OF MATTER State - the form in which matter exist SOLID

Particles are tight definite shape EXAMPLES OF SOLIDS LIQUID

no definite shape particles are loosely tight takes the shape of its container EXAMPLES OF LIQUID GAS no definite shape

also takes the shape as its container particles are spreaded EXAMPLES OF GAS State Definite Shape Definite Volume

Solid YES YES Liquid


NO THE 4TH MATTER Plasma is the 4th state of matter It is like Gasses but the particles are made of free electrons EXAMPLES OF PLASMA

ABSOLUTE ZERO The atoms in matter vibrates even though you can not see it vibrates. Absolute Zero is the degrees that atoms can not move at all It is at -273.15 Celsius or 459.67 Fahrenheit Question 1

What state is this? (Inside) Question 2 What is this state?

Question 3 State Definite Shape Definite Volume Solid

Liquid YES NO Gas Fill in the blank

STATE CHANGES Changing from one state to another state (liquid - gas ) -matter can change phases by adding heat or by removing heat. Melting - going from solid to liquid

(Ice -> water) Freezing - going from liquid to solid (water -> ice) Condensation- going from gas to liquid (clouds - rain)

Evaporation-going from liquid to gas (water - water vapor) Deposition - going from gas straight to solid without going in a liquid state in between (cloud - snow)

Sublimation- going from gas to solid without entering the liquid state (Water vapor ice Phase changes do not change the substance but just change the motion (water and ice are the same) more heat = more movement of molecules

less heat = less movement of molecules Phases that heat is added Phases that heat is removed

Melting Freezing Evaporati on Condensati

on Question 1 What is Melting? Question 2

What two things can cause state changes? Question 3 What is the order of states

from low energy to high energy? CHANGES OF MATTER There are two types are changes Physical Changes Chemical Changes

PHYSICAL CHANGE Physical Change- A change to the matter on how it looks but not change the matter completely Examples - cutting, coloring, CHEMICAL CHANGE Changes the composition of the matter Example: burning paper changes the matter of the paper to crisp

dust Not easily reversed or reversible (you can not revert crisp dust back to paper MIXTURE A mixture is a compound made of two matter than is not combined chemically Examples

Salad ( leaves- dressing) Cereal ( milk - cereal) Salt Water ( Salt + Water) SOLUTION - a liquid mixture in which the minor component dissolves into the major component and is spread throughout Examples

Saltwater ( salt - minor ; water- major) Syrup ( sugar - minor; water - major) Vinegar (acid - minor; water - major) Question 1 What of these are not a Physical Change

Coloring Cutting Burning Breaking Question 2

What of these are not a Chemical Change Rusting Cutting Burning Cooking

PROPERTIES OF MATTER A description about the certain matter that can be measured or observed. THINGS TO THINK ABOUT How It Looks (Shiny ,Dull, Color, etc.)

How It Feels (Hard, Soft, Rough , Smooth, etc.) How It Smells (Sweet, Sharp, Terrible, No Smell, etc.) How It Sounds (Loud, Soft, Echo, No Sound, etc.) What It Does (Bounce, Stretch, Tear, Break, Magnetism etc.)

COLOR We can use color to identify different matter rock ( gray to brown) sky ( blue to gray in stormy nights) fire ( red ) ocean ( deep blue)

SIZE Some matter are bigger than others A normal size pencil is smaller than a desk A baseball ball is smaller than a basketball MALLEABILITY Malleability is a property in which it measures how good that matter can be smashed down

Clay can be smashed to be thin while bricks will break if a hammer smash it DUCTILITY Measures how a certain matter can be stretched and pulled SOLUBILITY How well can a certain matter dissolve in

water DENSITY The amount of mass per volume D = Mass Volume

THERMAL CONDUCTIVITY How well can a material conduct heat. Examples Metal ( become hot if expose to a heat source) FLAMMABILITY How well can the certain matter be set on fire

THINK OF A PROPERTY THAT WAS NOT LISTED!!! absorption albedo area

brittleness boiling point capacitance color concentration density dielectric constant ductility

distribution efficacy electric charge electrical conductivity electrical impedance electrical resistivity electric field

electric potential emission flexibility flow rate fluidity frequency inductance intrinsic impedance

intensity irradiance length location luminance luster malleability

magnetic field magnetic flux mass melting point moment momentum permeability permittivity

pressure radiance solubility specific heat resistivity reflectivity spin strength

temperature tension thermal conductivity velocity viscosity volume wave impedance
