DENSITY AND SPECIFIC GRAVITY Flashcards
Mass per unit volume of a substance
Density
What is density expressed as
Grams per cubic centimeter
What is the density of water?
1g/cc
Formula of density
Density = Mass/Volume
Is a ratio, expressed decimally, of the weight of a substance to the weight of an equal volume of a subtance
Specific Gravity
The weight of a substance relative to the weight of a standard
Relative Value
Formula for Specific Gravity
Specific Gravity = Weight of substance/Weight of Equal Volume of Water
What substances are lighter than water?
A specific gravity of less than 1
What substances are heavier than water?
Specific gravity is greater than 1
Concrete number
Density
Units of measure varies
Density
Maybe expressed as
1g/mL, 1000g/L, 62.5 lb/cu ft
