Solid
What is a state of matter in which the substance has definite shape and volume?
100
Gas
What is a state of matter in which the substance takes the shape of its container and is of low density compared to solids and liquids. It has expansion and contraction with changes in temperature and pressure?
100
Liquid
What is a state of matter in which the substance had definite volume but takes the shape of the container?
100
Atom
What is the smallest part of an element that can exist and still retain the characteristics of that element?
100
Chemistry
What is the study of matter-its properties, composition, and changes?
200
Filtering
What is the process of passing a mixture of a liquid and a solid slowly through paper or another porous substance in order to remove the solid from the mixture?
200
Heterogeneous mixture
What is a mixture of varying composition;e.g. a mixture of soil and sand may have more of one component in one sample than in another sample of the same size taken from elsewhere in the mixture?
200
Homogeneous mixture
What is a mixture called when every part of the material is the same as every other part and their properties are blended and every part of the mixture is the same?
200
Mixture
What is all of the atoms or molecules in this may come from a variety of substance. This can be a number of pure substances brought together. In most cases the pure substances can be isolated by relatively simple procedures?
200
Boil
What is to change from a liquid to a gaseous state. This point of water needs to be 100 oC?
300
Adhesion
What is the force of attraction between the surface of unlike bodies such as a solid and a liquid?
300
Cohesion
What is the sticking together of like molecules; such as water being attracted to another water molecule?
300
Surface Tension
What is a property of liquids such that their surfaces behave like a thin, elastic film?
300
Density
What is the amount of mass in a substance per unit of volume?
300
Decanting
What is pouring off the top layer without disturbing the layers or the sediment below?
400
Distillation
What is the process of vaporizing and then condensing a liquid?
400
Chemical Change
What is a change in substances that will react with another. In this change the products are very different from the reactants. This change is irreversible?
400
Solvent
What is the substance that does the dissolving in a solution?
400
Suspension
What is a mixture in which very small particles of a solid remain suspended without dissolving?
400
Physical Change
What is a change in a substance where no new substances are formed through the substance; itself takes on different characteristics; e.g. a solid becoming a liquid. These changes are reversible; i.e. the substance can be returned to its original state or recovered from a mixture?
500
Compound
What is a pure substance containing two or more elements united chemically? The molecules of the compound are all the same. Water is this consisting of hydrogen and oxygen in a ratio of 2:1?
500
Saturated
What is referring to a solution that is not able to hold anymore solute at that temperature?
500
Solute
What is the substance dissolved in a solution?
500
Solution
What is a homogeneous mixture in which the solute is uniformly distributed throughout?
500
Product
What is a substance obtained from one or more other substances as a result of a chemical reaction?
