Matter, Solutions, and Gas Laws

Georgia Performance StandardsSPS2. Students will explore the nature of matter, its
classifications, and its system for naming types of matter.
a. Calculate density when given a means to determine a substance’s mass and volume.
SPS5a. Compare and contrast the atomic/molecular motion of solids, liquids, gases and plasmas.
SPS7d. Explain the flow of energy in phase changes through the use of a phase diagram.

Properties of Matter• Physical Property- a characteristic of a
material that you can observe without changing its identity.
• Ex.- Color, ____________, __________, magnetic quality, malleability, ability to flow, odor, state of matter, density, melting point…

Density• The amount of mass per unit volume• Density= mass/volume
Explain why the density of an object does not change if you cut it into smaller pieces. IF YOU CUT A PIECE OF STEEL IN HALF, THE MASS IS CUT IN HALF, AND THE VOLUME IS CUT IN HALF…
Example: 20 grams of steel cut in half is 10 grams (mass) and the volume is cut in half from 5 cubic centimeters to 2.5 cubic centimeters.
mass/volume mass/ volume20g / 5 cm3 = 4 g/ cm3 or 10/ 2.5 cm3 = 4 g/ cm3
SAME DENSITY!!!
DENSITY OF AN MATERIAL NEVER CHANGES... NO MATTER HOW BIG OR SMALL!!

Distillation• physical change• The process of separating a
mixture by its boiling
pointsExamples:Making alcohol,
separating petroleum, or salt water

Petroleum: Fractional DistillationOil was formed from the remains of animals and plants that lived millions of years ago. Over the years, the remains were covered by layers of mud. Heat and pressure from these layers helped the remains turn into what we today call crude oil . The word "petroleum" means "rock oil" or "oil from the earth."
Other products made from petroleum include: ink, crayons, bubble gum, dishwashing liquids, deodorant, eyeglasses, records, tires, ammonia, and heart valves.

Properties of MatterChemical Property-- describes its "potential" to undergo
some chemical change or reaction because of its composition
• Chemical properties can only be observed by changing a substance's identity. Flammability, Reactivity, etc
• Once a chemical change has occurred a NEW SUBSTANCE OR SUBSTANCES is/are produced with totally new physical and chemical characteristics.

Conservation of Mass• During a chemical reaction, energy is taken in or
given off
The Law of Conservation of Mass states mass is neither created or destroyed.
• The mass of the reactant(s) is equal to the mass of the products(s).
reactants products

Composition of MatterPure Substances and Mixture
Pure Substances– Elements and Compounds
A. Elements – all atoms in the substance are alike
• 90 elements found in nature• 20+ made in laboratories• Atom is the smallest particle of an element that
still retains the characteristics of that element• Examples: copper, gold, hydrogen, carbon
(anything on the periodic table)
![Page 15: Matter, Solutions, and Gas Laws. Georgia Performance Standards SPS2. Students will explore the nature of matter, its classifications, and its system for.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649ebd5503460f94bc74dc/html5/thumbnails/15.jpg)
2. Compounds– consisting of two or more elements bonded together (chemically combined) in a fixed mass ratio that can be split into simpler substances.
• Examples: water (H20), carbon dioxide (CO2), sugar (C6H1206), hydrochloric acid (HCl), salt (NaCl)
Molecule -- the smallest particle of a compound that still retains the characteristics of that compound
![Page 16: Matter, Solutions, and Gas Laws. Georgia Performance Standards SPS2. Students will explore the nature of matter, its classifications, and its system for.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649ebd5503460f94bc74dc/html5/thumbnails/16.jpg)
Mixtures:• 2 or more materials mixed together BUT
NOT CHEMICALLY combined, they still retain their own chemical makeup.
• Unlike compounds, mixtures do not always contain substances in fixed proportions.

Heterogeneous Mixtures2. Suspension-- mixture between liquids or
liquids/solids that will settle out upon standing.
• Examples: Italian dressing, pond water, oil and vinegar

Homogeneous Mixtures1. Solution-- A mixture where one material is _______________ in another…• the dissolved particles are so small you can’t see them
Parts of a solution:A. ___________– the particles dissolved
in the solution• Examples: sugar, Koolaid mix, saltB. __________– the substance in a solution in which the particles
dissolve• Usually water

An Alloy is a SolutionAlloy-- a solution of two or more elements,
usually metal and metal.
• brass– zinc and copper
• stainless steel– copper, nickel and iron
• Pewter– lead, copper, tin
• White gold– nickel, palladium and gold
• Rose gold – copper and gold
• Bronze– aluminum and copper
What are 3 reasons we make alloys?

Homogeneous Mixture2. Colloid: A homogeneous mixture that contains some particles that are larger in size, but still evenly distributed throughout
•Does not settle upon standing
Tyndall Effect– scattering of light due to larger particles… causes milky/cloudy color in colloids
Example… milk, fog, peanut butter, butter, mayonnaise, yogurt…

Gas Laws1. Charles Law
STATES…As ___________ goes up, __________ goes up (if pressure stays same)
• Remember CTV• Volume is directly proportional to temperature
Example: basketball in the summer vs. basketball in the winter

Gas Laws2. Boyle’s LawSTATES..If the ___________ goes down, then the
___________ will go up (if the temperature stays constant)
• Remember BVP• Pressure is indirectly proportional to volume
Larger volume, less pressure
smaller volume, pressure goes up
