1. DENSITY
DENSITY = MASS (REFERENCE TABLE)
VOLUME
Size and shape of the material- .
An object made of the same uniform material- A B
Mass = 24 grams Mass = 12 grams
Volume = 8 cm Volume = 4 cm3
Density = grams = Density = grams =
cm cm3

2. GRAPH OF DENSITY
DENSITY
grams/cm3
MASS

No matter where you are on the density line-

4. In general –
to determine the density of the line.
Object A – (greatest density)
Object B –
Object C –
Object D (least density)
FLOATATION - of objects is described in terms of density.
Objects that have a greater-
Objects that have less-
Objects that have the same-

5. PHASES OF MATTER are described in terms of -
In general objects made of the same material will sink (greatest density)
and will float (least density).
FACTORS THAT AFFECT DENSITY
Solid – temperature
pressure
dense
Vapor temperature

6. This can be expressed in terms - .
density -
temperature -
density -
pressure

7. WATER
Water is the exception to the general rule of density.
***** Water has its maximum density in the
‘Celsius
At 3.98 degrees Celsius, the density of liquid water is equal to
