• These particles can be tightly bound and close together or they can be loosely connected and widely separated
• Change in Temperature and pressure can cause transition from one state to other
• Chemical identity of matter remains same in different states
• Physical properties change with change of state
• There can be matter within matter.
• Matter cannot be destroyed or created.
• It can be transformed to different forms.
