-The energy that results from the breaking or formation of chemical bonds is chemical energy.
-The energy that matter possesses because of its position is potential energy.
-The energy that matter has because of its motion is called kinetic enerygy.
-A measure of the average kinetic energy of the particles in a sample of matter is temperature.
-The sum of the total kinetic energy of the particles in a sample of matter is heat.
-The fact that mass and energy cannot be created or destroyed is the fundamental concept of the theme of conservation.
-"In any chemical or physical process, energy is neither created nor destroyed" is a statement of the law of conservation of energy.
K=C+273
C=5/9(F-32)
F=9/5C+32
-Specific heat capacity is the amount of heat energy needed to raise the temperature of one gram of a substance 1K.
-The specific heat capacity of a given substance is unique to that substance.
-E=mc2 is a statement of the relationship of mass to energy.
-For every investigation, the scientific method is a logical set of procedures.
-The reason for organizing, analyzing, an classifying data is to find relationships among the data.
-A control is meant to eliminate error by serving as a comparison for other data and increase confidence in collected data.
-A testable statement used for making predictions and carrying out further experiments is a hypothesis (educated guess).
-A plausible explanation of a body of observed natural phenomena is a scientific theory.
-The validity of scientific concepts is evaluated by testing hypotheses.
-A statement or mathematical equation that describes a basic fact or relationship found in the universe is a law.
-A theory is an accepted explanation of an observed phenomenon until repeated data and observation conflict with the theory.
-A measurement that closely agrees with the accepted values is said to be accurate.
-A measurement is said to have good precision if it agrees closely with other measurements of the same quantity.
-If some measurements agree closely with each other but differ widely from the actual value, these measurements are precise but not accurate.
-Poor precision in scientific measurement may arise from both human error and the limitations of the measuring instrument.
-Precision pertains to reproducibility of measurements, agreement among numerical values, and precise.
-Five darts strike near the center of the target. Whoever threw the darts is both accurate and precise.
-A chemist who frequently carries out a complex experiment is likely to have high precision.
-When determining the number of significant digits in a measurement, all nonzero digits are significant.
-In division and multiplication, the answer must not have more significant figures than the number in the calculation with the fewest significant figures.
