Properties of Matter

1. MATTER
1. The properties of matter.

2. Air: is it matter?
Why does a full air balloon weigh more
than an empty balloon?

3. Why doesn’t water enter in the glass?

4. Properties of matter
• Length.
• Surface or area.
• Volume.
• Mass.
• Density.
• Temperature.

5. Length
Length is the distance between two bodies.

It is measured in metres (m).

We use rulers and measuring tapes when
we measure length.

1 km = 1000 m
1 hm = 100m
Length units
1 dam = 10 m
1 dm = 0,1 m
1 cm = 0,01m
1 mm = 0,001m

6. Surface
Surface is the space occupied by two dimensions:
length and width.

It is measured in square metres (m2).

Surface units
1 km2 = 1000000 m2
1 hm2 = 10000m2
1 dam2 = 100 m2
1 dm2 = 0,01 m2
1 cm2 = 0,0001m2
1 mm2 = 0,000001m2

7. Volume
Volume is the total space occupied by a body.

It is often measured in litres although the
International System volume unit is the
cubic metre (m3).

1 m3
= 1000 dm3 = 1 kL
1 dm3
= 1000 cm3 = 1 L
1 cm3
= 1 mL
Volume units

8. Volume
The volume of geometric solids can be obtained
using mathematical formulae.

The volume of liquids can be measured using
measuring cylinders.

9. Volume
How can you find out the volume of an irregular
solid like a stone?


10. Mass
Mass is the amount of matter in a body.

It is measured in kilograms and grams.

1 t = 1000 kg
1 kg = 1000 g
1 hg = 100g
Mass units
1 dag = 10 g
1 dg = 0,1 g
1 cg = 0,01g
1 mg = 0,01g

11. Mass
The mass can be measured with scales.


12. Density
Density measures how concentrated the mass is.

The density is expressed in kg/m3 or in g/cm3

To measure the density of an object we can
determine the mass and the volume of the object
and divide both measurements:

Density =
Mass
Volume

13. Density
Density =
Mass
Volume
240 : 1000 = 0,24 g /cm3 11290 : 1000 = 11,29 g /cm3
1000 cm3
cork lead

14. Air 0,012
Alcohol 0,8
Water 1
Some substances density (g/cm3)
Aluminium 2,7
Copper 8,9
Silver 10,5
Lead 11,3
Iron 7,8
Mercury 13,6
Gold 19,3

15. Matter is anything that has both mass and
volume (occupies space)
Same volume and
different mass.
Same mass and
different volume.
Same shape and
different material.
Same material,
different shapes.
