LECTURE # 4 : MATTER: ITS PROPERTIES, CHANGES AND COMPOSITION
States of Matter
Matter exists in three familiar states – solid, liquid and gas
...
Plasma state is considered as the fourth state of matter
...
Examples are flame, lightning and sun
...
Physical Properties are those which can be observed and measured without necessarily
changing their composition
...
b
...
Example: flammability, acidity, stability
c
...
These are inherent to the
substance and remain the same regardless of whether the quantity is small or large
...
Extensive Properties are dependent on the amount of materials
...
Example: mass, height, length
Changes in Matter
1) Physical Change occurs when matter changes in shape, size, or state but not in composition
...
Freezing of water into ice
2) Chemical Change results when matter undergoes a change in composition
