__________ is a physical property which represents the relationship between the mass of a substance and its volume.
Density = __________ / __________
1) Mass 2) Volume
Density is commonly expressed in the following units for the following substances: Solids = __________ / __________ Liquids = __________ / __________ Gases = __________ / __________
1) g / cm^3 2) g / mL 3) g / L
Volume is proportional to __________ x __________ x __________
1) Length 2) Width 3) Height
Normally the volume of an object can be found by the displacement of __________: __________ is added to a graduated cylinder and the volume is read. After the initial volume has been obtained, an object can be dropped into the graduated cylinder, further displacing the __________. The volume is simply the difference between the new volume with the object and that of the original volume.
1) Water 2) Water 3) Water
A third method for determining volume is by __________ method. Objects in water are lighter (__________ less but have the same __________) than in air. This is because the displaced liquid pushes back on the object with a force equal to the __________ of the liquid displaced. The object will have an apparent loss of __________ equal to the mass of the __________ displaced.
1) Archimedes 2) Weigh 3) Mass 4) Mass 5) Mass 6) Liquid
In making laboratory experiments, experimental errors occur because of: 1. The __________ being used, or 2. __________ error.
1) Equipment 2) Human
__________ refers to how close a measurement is to the accepted value or theoretical value. Errors related to this are called “percentage error” are calculated by the equation: (|__________ value – __________ value| / __________ value) x100%
