made up of

when there is not enough neutrons

protons and neutrons make up the nucleus

electrons are in the electron shells

necessary for an experiment

dependent variable changes based off of the independant variable

melting

freezing

types of changes in science

common physical changes that occur

a bar graph is similar to a line graph, bar graph uses a rectangular box and a line graph uses lines

kinetic theory explains the gas laws

v, t, & p is all used with gas law equations

when using the metric system, you have to convert inches, meters, and grams

a valence electron is the number of electrons in the last electron shells
