A type of matter composed of varying proportions of two or more substances that are just physically mixed, not chemically bonded.

Concentrated and has a high capacity to do useful work. Examples are very high-temperature heat, nuclear fission concentrated sunlight, high-velocity wind, and energy released by burning natural gas. gasoline, or coal.

An element having the same atomic number but different mass number.

Basic unit of inheritance found in the DNA molecules that contain genetic information.

Carbon, hydrogen and oxygen. Ex: glucose

A measure of an energy source's capacity to do useful work.

Formed by monomers called amino acids.

All atoms have the same number of atoms.

Compounds of carbon, hydrogen and chlorine atoms. Ex: insecticide DDT(C14H19C15)

Not highly concentrated, often located deep underground or dispersed in the ocean or atmosphere, and usually has little potential for use as a resource.

A mixture that is uniform throughout which like it might be just one substance.

Thare is no change in its chemical composition.

A compound carbon of few number of carbon atoms are present.

Dispersed and has little capacity to do useful work. An example is heat dispersed in the moving molecules ofa large amount of matter (such as the atmosphere or an ocean) so that its temperature is low.

A type of matter in which all samples have fixed composition and identical properties.

An atom or geoup of atoms with one or more positive or negative electrical charges.

Changes in the nuclei of its atoms(radioactive decay, nuclear fission, nuclear fusion)

A mixture that has at least two or more components can be observed.

Second building block of some types of matter.

All elements are made up od atoms.

Anything that occupy space and has mass.

Highly concentrated, typically found near the earth's surface, and has great potential for use as a resource

Contains at least two carbon atoms combined with atoms of other elements.

There is a change in chemical composition of the substance involved.

Special DNA molecule together w/ proteins.

Measure of how useful a given sample of matter is as a resource for humans.

Compounds of hydrogen and carbon atoms. Ex: CH4 simplest natural gas, octane: component of gasoline

Smallest and fundamental structural and functional units of life.smallest and fundamental structural and functional units of life.

Composed of two or more elements chemically bonded in a definit fixed ratio by mass.

Cellulose and starch, which consist of 2 or more monomers of simple sugars such as glucose.
