changes in states of matter. (C2.2A, C2.2B, C4.3A, C4.3B,C5.2B))

A chemical change does not always occur when substances are combined.
Accuracy in measurement can be expressed through the use of significant digits and percent error.
Chemical changes occur when matter reacts and produces new substances; physical changes yield
different forms of the same substance rather than a new substance.
Every experiment provides useful results, whether or not the results match the hypothesis. Evidence of
chemical change includes color change, gas formation, solid formation and temperature change.
Mathematical and scientific solutions should be accurate, reasonable and use appropriate notation.
Scientific investigations follow processes that require systematic and logical development, observation,
and careful analysis.
Scientific investigations generally lead to new questions.
Substances may be classified by their physical and/or chemical properties.
The foundation of scientific theory is replicable investigations.
Through repeated inquiry, patterns emerge and theories are proposed.
Boiling and Evaporation are not the same
Energy is absorbed or released as a substance changes from one phase to another.
Energy may be transferred from one object to another.
Heat and temperature are not the same.
Heating is the transfer of energy from one substance to another. As temperature increases, average
kinetic energy increases.
Molecules that comprise matter are constantly in motion.
