PHYSICAL SCIENCE PRELIM TO FINALS., Exams of Science education
atomic theory - ANSWERa theory that states that all matter is composed of
tiny particles called atoms.
charge - ANSWERa measure of the extra positive or negative particles that an
object has
relative mass of subatomic particles - ANSWERneutron-neutral
proton-positive
electron-negative
amu
solid - ANSWERclose together
vibrate
liquid - ANSWERslide past
, gas - ANSWERspread
rarely touch
charles law - ANSWERvolume correlates with temperature
temp goes up, volume goes up
boyles law - ANSWERvolume correlates with the pressure
pressure goes up, volume goes down
chemical properties - ANSWERcharacteristics that can only be determined by
a chemical reaction and a chemical change in a substance
physical properties - ANSWERthe characteristics of a substance that can be
observed or measured without changing the substance
density - ANSWERthe amount of mass in a given volume
elements - ANSWERa molecule composed of one kind of atom; cannot be
broken into simpler units by chemical reactions.
organization of the periodic table - ANSWERthe elements into periods (rows)
and groups (columns) by increasing atomic number. elements with similar
properties are in the same group
atomic mass - ANSWERweighted average of amount of isotopes in nature
