3. Measuring volume using a
measuring cylinder
• Place the
measuring cylinder
on a flat surface.
• Position the eye at
the same level as
the liquid level.

4. Volume of water = 40 cm3

5. What is the volume of the marble?

6. (1) Before marble put in,
water level = 60 cubic
cm
(2) After marble put in,
wtaer level = 62.5
cubic cm
(3) Volume of the marble
= 62.5 cubic cm – 60
cubic cm
= 2.5 cubic cm

7. Liquids
A liquid has no definite shape
but has a definite volume.
Having a definite volume makes a liquid
hard to be compressed.

8. Gases
A gas has no definite shape
and no definite volume.
Therefore, it can be COMPRESSED easily.
