Mass - ANSthe amount of matter in the object and is independent of where the object is. (Exp.1)
Weight - ANSThe force of gravity on the object and is dependent of where the object is. (Exp.1)
Volume - ANSLength is 3 dimensions. (Exp.1)
Density - ANSd=mass/volume in g/mL (Exp.1)
Experiment 1 - ANSInvolves finding the density of a pre-1983 penny, a post 1983 penny, an
unknown liquid, and an unknown solid. Measuring the pennies with a meter stick, ruler, and
caliper.
Significant Figures - ANSIncludes all of the digits in the number that you know with certainty
plus one final digit that you estimate
Accuracy - ANSRefers to how close a measurement is to the true value
Precision - ANSHow close the measurements are to one another
Displacement Method - ANSSubmerging a solid in water to find its volume.
Law of Definite Proportions - ANSA chemical compound always contains its component
elements in a fixed ration
Hydrate - ANSIonic compounds that have water as an integral part of their molecular structure,
and this water is present as a definite fixed mass percent of the same. (not a wet compound,
water is incorporated in chemical bonding).
Mono - ANSone
Di - ANStwo
Tri - ANSthree
tetra - ANSfour
penta - ANSfive
hexa - ANSsix
