|
Matter |
Anything that occupies space and has weight. |
|
|
Physical properties |
Describe what a substance is Characteristics w/ which we describe matter without changing its identity. |
|
|
Extensive property |
Vary with a change in quantity, depend on the amount ex. Mass, volume, weight, size. |
|
|
Intensive Property |
Do not vary or depend on the amount ex. Odor, color, solubility, melting point. |
|
|
Chemical Properties |
Tells what a substance does Characteristics which can be observed as a result of change in identity. |
|
|
Plasma |
An ionized gas |
|
|
Ionized gas |
A gas into which sufficient energy is provided to free electrons from atoms and to allow both ions and electrons to both exist. |
|
|
Bose-Einstein condensate |
A gaseous superfluid phase produced by atoms cooled to temperatures very near to absolute zero. |
|
|
Physical change |
A process which the identifying or intensive properties of the substance involved remain unchanged No new substance produced. |
|
|
Phase change |
Change of matter from one state to another. |
|
|
Sublimation |
Change from solid phase directly to gaseous phase without any liquid being formed. |
|
|
Chemical change |
Process in which the composition or intensive properties of the substance involved are changed. |
|
|
Elements |
Simplest substance that make up matter Building blocks of matter. |
|
|
Metals |
Have luster Reflect light Ductile |
|
|
Nonmetals |
Seldom reflect light Not ductile not malleable Little luster. |
|
|
Metalloids |
Have properties characteristic of both metals and minerals; heat semiconductor |
|
|
Compound |
Substances made up of two or more elements which are chemical combined. |
|
|
Compound |
Have definite proportion by weight and different properties. |
|
|
Mixtures |
A combination of two or more substances mixed together physically. |
|
|
Mixtures |
No definite proportion or composition Can be separated into their Component substances by physical means and retain properties of individual substances. |
|
|
Homogeneous |
Salt-water mixture e.g. same composition throughout |
|
|
Heterogeneous |
Different composition e.g sugar and sand. |
