States Of Matter
Matter can be classified into 3 states:
|1)They have fixed shape and volume||They do not have fixed shape but have fixed volume||They do not have fixed shape and volume|
|2)They cannot be compressed||They cannot be compressed||They can be compressed easily|
|3)They have high density||They have moderate density||They have low density|
|4)They do not flow||They flow easily||They flow easily|
|5)They do not fill their container||They do not fill their container||They fill their container|
|6)The forces of attraction are strong||The forces of attraction are less strong than solids||The forces of attraction are weak.
|7)Kinetic energy is least||Kinetic energy is more than solids||Kinetic energy is maximum.|
|8)Particles are closely packed||Particles are not close as in solids||Particles are much farther apart from one another.|
|9)ForEx: Chair,table,chalk,book||For Ex:Water,petrol,cold drinks||For Ex:Oxygen,nitrogen,helium|
Aquatic animals can breathe under water due to the presence of dissolved oxygen in water.
LPG-Liquified Petroleum Gas
CNG-Compressed Natural Gas
Gases have high compressibility.They can be compressed into very small volumes by applying large pressure.Due to its high compressibility,fairly large mass of gas can be put in a small metal cylinder by compression.Such gas cylinders can be easily transported from one place to another.
