Vocabulary for Smithsonian STC-MS Matter & Its Interactions Unit
Terms in this set (13)
The smallest unit of matter that cannot be broken down by ordinary chemical reactions.
Chemical and physical properties that define attributes of a pure substance and are independent of the same amount. Characteristic properties can be used to identify pure substances.
A decrease in the volume of matter.
The mass of a substance that fills one unit of volume. It is usually measured in grams per cubic centimeter (g/cm3).
A labeled drawing that explains or shows the parts of something. A diagram is a type of model.
An increase in the volume of matter.
A measure of the amount of matter in an object. In the metric system, mass is measured in kilograms (kg) or grams (g).
