| What is the definition for mass? | Amount of matter in an object |
| What is the definition for volume? | Amount of space an object occupies |
| How many phases of matter exist? | 4 |
| What phase of matter contains the most energy? | Plasma |
| What state of matter has a definite volume but an indefinite shape? | Liquid |
| What state of matter can the particles only vibrate? | Solid |
| What word describes a solid that lacks internal structure, thus having some properties of a liquid? | Amorphic or amorphous |
| What is the resistance of a liquid to flow? | Viscosity |
| What two variables does Boyle's law take into consideration? | Pressure and volume |
| What two variables does Charle's law take into consideration? | Temperature and volume |
| What is the relationship between temperature and volume in Charle's law? | Directly proportional |
| What is the relationship between pressure and volume in Boyle's law? | Inversely proportional |
| What is the equation for Boyle's law? | P1V1=P2V2 |
| If you have 90 g of ice and let it melt, what mass of water will you have? | 90 g |
| If you have 90 g of water and freeze it, what will happen to the volume as it freezes? | Expand or get bigger. |
| A property of matter than can be observed without changing the identify of the substance is called a(n)________ property. | Physical |
| What law states that matter can not be created or destroyed, and that in a phase change the amount of matter stays the same? | Law of Conservation of Mass (Matter) |

| What is a physical combination of two or more elements or substances called? | Mixture |
| What is the simplest pure substance? | Element |
| What is the smallest unit of an element with properties of that element? | Atom |
| How many elements occur naturally on Earth? | approximately 90 |
| The Law of Definite Proportions applies to what type of matter? What does it state? | Elements present in a compound have to occur in fixed proportions. |
| What is the chemical formula for hydrochloric acid? | HCl |
| Is milk souring a physical or chemical change? | Chemical |
| Is stirring milk a physical or chemical change? | Physical |
| Mixtures that look the same throughout are called what? | Homogeneous mixtures |
| What are the three types of mixtures? | Solution, suspension, and colloid |
| What type of mixture has the largest particle size? Thus, what will it do upon standing? | Suspension; settle out |
| Is Raisin Bran cereal a homogeneous or heterogeneous mixture? | Heterogeneous |
| Your mom makes a pitcher of orange Kool-Aid and puts it in the refrigerator. Is this an example of a homogeneous or heterogeneous mixture? | Homogeneous |
| What is the ability of a substance to burn called? | Flammability |
| What two types of mixtures exhibit the Tyndall effect? | Colloids and some suspensions |
| Are solutions homogeneous or heterogeneous mixtures? | Homogeneous |
| What is the name of the physical process used to separate two liquids that have different boiling points? | Distillation |
| Is reactivity to light a chemical or physical property? | Chemical |
| What metric prefix means 1000? | Kilo- |
| What metric prefix means 0.1? | Deci- |
| What metric prefix means 1/100? | Centi- |

| The factors that a scientist must hold the same from one group to another in an investigation are called ___. | Constants |
| What axis hold the independent variable on a graph? | X-axis |
| By what process does a solid turn into a liquid? | Melting |
| By what process does a gas turn into a liquid? | Condensation |
| By what process does a liquid turn into a solid? | Freezing |
| What is the melting point of ice? | 0 degrees Celsius |
| What is the freezing point of water? | 0 degrees Celsius |
| What is the name of the theory explains how the particles in a gas behave? | kinetic theory of matter |
| What is the term for vaporization that occurs only at the surface of a liquid? | evaporation |
| During what phase change does a solid turn directly into a gas without forming a liquid? | sublimation |
| What is the boiling point of water? | 100 degrees Celsius |
| If you have both liquid water and ice at 0 degrees Celsius, what is the explanation for why each exists at this temperature. Please be specific. | Liquid water has more heat energy than the ice at 0 degrees Celsius |
