One substance exist in three states - Give its example. With physical properties, chemical composition and characteristics.

Explanation

One substance exist different physical state. e.g., water, can exist as ice which is a solid, it can exist as liquid and it exist in the gaseous state as water vapour or steam.
Physical properties of ice, water and steam are very different. Each three states it is `H_(2)O` and their chemical composition are same in three states.
Characteristics of three states is depends upon energy of molecules and how can molecules combined in `H_(2)O`.
