COMPARING MASS
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.
Volume of water = 40 cm3
What is the volume of the marble?
(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
Liquids
A liquid has no definite shape but has a definite volume.
Having a definite volume makes a liquid
hard to be compressed.
Gases
A gas has no definite shape and no definite volume.
Therefore, it can be COMPRESSED easily.
