scientific method - Correct Answers -systematic approach to research
hypothesis - Correct Answers -tentative explanation for a set of observations
law - Correct Answers -consise verbal or mathematical statement of a relationship
between phenomena that is always the same under the same conditions
theory - Correct Answers -unifying principle that explains a body of facts and/or those
laws based that are based on them
, chemistry - Correct Answers -study of matter and the changes it undergoes
substance - Correct Answers -matter that has a definite or constant composition and
distinct properties
mixture - Correct Answers -combination of two or more substances in which the
substances retain their distinct identities
homogeneous mixture - Correct Answers -composition of the mixture is the same
throughout the solution, after sufficient stirring
heterogeneous mixture - Correct Answers -composition of mixture is not uniform
element - Correct Answers -substance that cannot be separated into simpler
substances by chemical means
compound - Correct Answers -a substanec composed of two or more elements
chemically united in fixed proportions
extensive property - Correct Answers -depends on how much matter is being
considered
intensive - Correct Answers -does not depend on the amount of matter being
considered
weight - Correct Answers -force that gravity exerts on an object
significant figures - Correct Answers -the meaningful digits in a measured or calculated
quantity
accuracy - Correct Answers -how close a measurement is to the true value of the
quantity that was measured
precision - Correct Answers -how closely two or more measurements of the same
quantity agree with one another
heat capacity (C) - Correct Answers -the amount of heat required to raise the
temperature of a given quantity of the substance by one degree Celsius.
calculating heat change - Correct Answers -q=ms(delta)T
q=C(delta)T
Hess's Law - Correct Answers -when reactants are converted to products, the change in
enthalpy is the same whether the reaction takes place in one step or in a series of steps
