Theory
a well-supported, comprehensive explanation
Chemistry
the branch of science that studies matter
Mass
the amount of matter in an object
Atom
smallest particle of an element
chemical change
change that produces new substances
Deductive reasoning
Takes a general principle and then draws a specific conclusion from the general concept.
Analytical chemistry
The study of the composition of matter, focusing on separating, identifying, and quantifying chemicals in samples of matter.
Volume
the amount of space occupied by an object
Element
simplest form of matter
distillation
a liquid is boiled to produce and vapor that is condensed
Scientific method
A process of observation, developing a hypothesis, and testing that hypothesis.
Inorganic chemistry
The study of chemicals that do not, in general, contain carbon.
Energy
the capacity to do work or transfer heat
Mixture
blend of two or more substances
condensation
change from a gas to a liquid
Inductive reasoning
Involves getting a collection of specific examples and drawing a general conclusion from them.
Organic chemistry
The study of carbon-containing chemicals.
Density
property of matter that measures how much mass is packed into a specific volume
Compound
substance containing two or more elements chemically combined
evaporation
to change from a liquid to a gas
Hypothesis
a proposed, testable explanation or educated guess for an observation
Physical chemistry
The study of the both the macroscopic and the atomic properties and phenomena in chemical systems.
Unit
used as a basis for measurement
Substance
matter that has the same composition and properties throughout
sublimation
change from a solid directly to a gas
