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
