C 14- Properties of Matter
All matter has properties that can be observed, described, and measured.

I. What is the Structure of Matter? A. Matter 1. Matter is anything that a. has __b. takes up__ _ 2. Mass is measure of the amount of _ in an object 3. Weight is a measure of how much pulls on the matter 4. Although an object’s mass is the same on the earth and moon, the _ is different 5. Conservation of Matter means a change in shape does not change AMOUNT of matter 6. Volume is amount of an object takes up a. Solid volume measured by length x width x b. Liquid volume poured into graduated cylinders c. Conservation of Volume means same amount of liquid not matter what shape container

B. Atoms and Molecules 1. __the smallest particle that can still be identified as the matter it came from 2. Each different kind of atom has different__ _ __3. Two or more atoms joined together make a__ _ a. Molecules have different properties from the atoms they are made from 4. Parts of an atom a. Nucleus is made up of _ & _ __b. Neutrons have__ _ __electrical charge c. Protons have__ _ electrical charge (1) The _ __of protons determines the kind of atom (2) The kinds of atom determines the atoms properties d. __ circle the nucleus, have _ __charge

C. Elements 1. Elements are matter made of only__ kind of _ 2. Water is not an element because it is made up of 2 elements, hydrogen and oxygen 3. Scientists have identified _ elements 4. Periodic Table, a way to organize elements, a. each cell represents one element b. Info about an element , (1) symbol of name, (2) Element’s atomic number is number of in atom’s nucleus D. Solids, Liquids, & Gases are States of 1. Solids keep own shape because its molecules are don’t _ __much 2.__ change shape and flow because particles are a little further apart 3. In a gas molecules move _, getting further apart until something stops them

II. What are Physical Properties and Changes A. Changing States of Matter 1. _ __causes the change in states of matter 2. Change in states of matter is a__ _ __change a. Chemical makeup (its molecules) are still the same just closer or further apart b. Solid to liquid is ___ __c.__ _ __causes liquid to become gas d. Gas to liquid is__ _ __e. Liquid to solid is__ _ f. Ice melts at F or __C g. Water becomes gas at__ F or _c h. __C is both a melting point and a freezing point of water depending on which stae water is changing TO i. Condensing point is__ _C j. To _ means to change from a solid to a gas without becoming a liquid

B. Melting and Boiling Point s 1. Describe a physical __of all matter 2. Differ depending on molecules involved

C. Density 1. A measure of how closely packed an object’s atoms are 2. Like boiling point, density is a__ _ property of matter 3. A substances’ density __not change, so a way to identify a substance 4. Every substance has its own density

D. Mixtures and Solutions 1.__ is a combination of 2 or more substances 2. Substances are __not permanently combined or evenly distributed a. can separate by boiling b. can separate by sifting c. can separate by filtering d. can separate by settling 3. Solution is special type of mixture, its substances are__ distributed 4. Kinds of mixtures a. Liquids in liquids b. Liquids in gas c. Gases in air E. Other Physical Changes 1. Breaking, crushing cutting, bending, melting, freezing, boiling, evaporation, recycling 2. Examples: tree to bat, yarn to a sweater, _ to _

F. Summary: Matter can change states at different ___. Boiling point and density are physical properties of matter. Matter can change physically by being put into mixtures or solutions or being broken, crushed, bent, melted or frozed. In physical changes the molecules making up a substance do NOT change.__ __ III. What are Chemical Properties and Changes A. Chemical Changes 1. Molecules making up a substance DO change 2. The change is called a__ _ _ __3. Evidence of chemical change : burning, change in color, gas, light or heat given off, 4. Chemical Properties a. __ of a substance is a measure of how easily it will burn b. Corrosion of metal is when oxygen reacts with metal to make rust c. Ability of a substance to go through a chemical change it its

B. Conservation of Matter 1. The amount of matter always stays the same in a chemical change 2. New form when substances react C. Summary: A chemical change is different than a physical change. A chemical change forms a NEW substance. Combustailtity and reactivity are chemical properties of substances.

IV. People in Science A. Claudia Benitez-Nelson 1. Is concerned about global 2. Atmospheric  __is linked to increase in Earth’s temperature 3. She’s trying to find out how much carbon dioxide the__ __absorb B. Yuan Tseh Lee 1. Is a scientist so he can make the__ _ better 2. Won a Nobel Prize for study of _ __ C. Career- Chemical Manufacture r 1. Produce__ _ that are used by manufacturing to make products 2. Some chemicals are
