The chapter covered thigns like chemical versus physical properties and changes, what chemistry is, the scientific method, significant figures and exponential notation, the International System of Units (SI), volume, mass versus weight, factor-label method, kinetic and potential energy, the calorie,
Things I might forget:
1. specific gravity is the density of something divided by 1--basically comparing the density of something to water.
2. specific heat is the amount of energy needed to raise the temperature of 1 gram of something 1 degree C.
