TermDefinition
density the mass per unit volume of a material describes how tightly packed a substance’s molecules are
derived unit unit of measurement obtained by combining SI units; for example, density is a derived unit formed by dividing an object’s mass by its volume
graph a visual display of information or data--such as line graphs, bar graphs, and circle graphs--organized to help people interpret, understand, or quickly find information
kelvin the SI unit of temperature; zero K=absolute zero (the coldest possible temperature, -273C)
kilogram the SI unit of mass; 1 kilogram (kg)=1000 grams (g)
liter the amount of liquid volume (L) that c=occupies the same volume as a cubic decimeter (dm3) and is slightly larger than a quart
mass a measurement of the amount of matter in a object; its SI unit is the kilogram (kg)
meter the SI base unit of length (m) 100 cm=1m
second the SI unit for time
SI International System of Units; standard, easy-to-use, worldwide system of measurement based on powers of 10. The SI standards are used by all scientists, and are a modern version of the metric system
standard in measurement, an exact quantity that everyone agrees to use as a basis of comparison; for example, a centimeter, meter, kilogram, cubic diameter, milliliter, liter, kelvin, joule, and so on
time the interval between two events; the SI unit for time is the second
volume the amount of space occupied by an object; volume units are found by combining other SI units of length
