1
, Chemical Answer: A substance that has the same composition and properties wherever it is
found
Chemistry Answer: The study of the composition, structure, properties, and reactions of matter
Conclusion Answer: An explanation of an observation that has been validated by repeated
experiments that support a hypothesis
Experiment Answer: A procedure that tests the validity of a hypothesis
Hypothesis Answer: An unverified explanation of a natural phenomenon
Observation Answer: Information determined by noting and recording a natural phenomenon
Scientific Method Answer: The process of making observations, proposing a hypothesis, testing
the hypothesis, and making a conclusion as to the validity of the hypothesis
Scientific Notation Answer: A form of writing large and small numbers using a coefficient that
is at least 1 but less than 10, followed by a power of 10
Celcius Temperature Scale Answer: A temperature scale on which water has a freezing point of
0 C and a boiling point of 100 C
Centimeter (cm) Answer: A unit of length in the metric system; there are 2.54 cm in 1 in
Conversion Factor Answer: A ratio in which the numerator and denominator are qualities from
an equality or given relationship. For example, the conversion factors for one metric conversion:
Cubic centimeter (cc or cm^3) Answer: The volume of a cube that has 1-cm sides.
Basic metric unit of voume for solids; equal to a mililiter.
Density Answer: The relationship of the mass of an object to its volume expressed as grams per
cubic meter (g/cm^3), grams per milliliter (g/mL), or grams per liter (g/L)
Equality Answer: A relationship between two units that measure the same quantity
Exact Number Answer: A number obtained by counting or by definition
Gram (g) Answer: The metric unit used in measurements of mass
International System of Units Answer: An international system of units that modifies the metric
system
Kelvin (K) Temperature Scale Answer: A temperature scale on which the lowest possible
temperature is 0 K
Kilogram (Kg) Answer: The SI unit of mass. There are 1,000 grams in a kilogram
Liter (L) Answer: The metric unit for volume that is slightly larger than a quart
Mass Answer: A measure of the quantity of material in an object
