it depend
on the quantity of matter.
extensive properties
it do not
depend on the quantity of matter.
Intensive properties
give examples of intensive properties
boiling point

what is the symbol for density and what it is called?
P
rho
formula for density
p=m/v
it can be used to identify a particular element or
compound.
density
specific gravity is also known as _____________-
relative density
is the ρ of a substance divided by the ρ of water
specific gravity
formula for specific gravity
specific gravity substance= Psubstance/Pwater
used to measure specific gravity
pycnometer
Calculated by dividing the weight by the volume of the substance
density
Calculated by dividing a substance’s density with the density of water
specific gravity
Represented in absolute term
density
Represented in relative term
specific gravity
represented in kg/m3
density
Does not have an SI unit
specific gravity
Used in domestic and commercial applications
density
Used in industries to measure the concentration of solutions
