UNIT 2: MASS, VOLUME AND DENSITI.
Matter
anything that occupies volume and has mass.
VOLUME:
The volume
of an object is the space it occupies.
The unit of volume in the international System is the
cubic meter. (m3)
1.000 l = 1m3
LIQUIDS:
There a lot of laboratory instruments for measuring
liquid volumes.
Pipette.
Graduated cylinder.
Measuring volume
1)
SOLIDS WITH REGULAR SHAPES.
We calculate the volume using formulas.
Other Solids
The change in volume of the liquid is equal to the
volume of the solid.
DENSITY
Density describes
the “concentration” of mass in the volume it occupies.
d = m / V
