Matter that has uniform and unchanging chemical composition.
What is Substance.
100
Altering a substance without changing the composition. - cutting, bending, and melting.
What is Physical changes
100
Combination of two or more pure substances in which each pure substance retains its individual chemical properties.
What is Mixture
100
Pure substance that cannot be separated into simpler substances by physical or chemical means.
What is Elements
100
Definite shape and volume.
What is Solid
200
Characteristic that can be observed or measured without changing the substance.
What is Physical Property.
200
Alters the chemical composition of a substance. Burning, rusting, and tarnishing.
What is Chemical change
200
One that does not blend smoothly throughout and in which the individual substances remain distinct.
What is Heterogeneous mixtures
200
Organized elements
What is Periodic table
200
Definite volume and no shape.

300
Depends upon the amount of substance. - mass length and volume.
What is Extensive physical property
300
States that mass is neither created nor destroyed.
What is Conservation of Mass
300
Constant composition throughout. - If you took a sample from top it would match the bottom.

Combination of elements that are combined chemically.
What is Compounds
300
No shape or volume
What is Gas
400
Doesn’t depend on amount. - density, color, melting, and boiling point.

400
States that mass is neither created nor destroyed in any process.
What is Law of Conservation of Mass.
400
Technique that uses a porous barrier to separate a solid from a liquid.
What is Filtration
400
Regardless of amount, a compound is always composed of the same elements in the same proportions by mass.
What is Law of Definite Proportions
400
Gas like mixture of + and - pieces of matter.
What is Plasma
500
Ability of a substance to combine with or change into one or more other substances.
What is Chemical Property.
500
Shows the relationship between the reactants and products in a chemical reaction.
What is Chemical equation
500
Technique that is based on differences in the boiling points of the substances involved.
What is Distillation
500
States when different compounds are formed by a combination of the same elements, different masses of one element combine with the same relative mass of the other element in a ratio of small whole numbers.
What is Law of Multiple Proportions
500
Vapor refers to the gaseous state of a substance that is a solid or liquid at room temperature.
