Question

Ice water and steam are three states of substances and a different substances justify

Answer 1

Answer:

solid state.. when it is in Ice form

liquid state... when it is in the form of water

gaseous state.. when it is heated

Answer 2

Freezing of water changes it's state from liquid to solid, i.e, ice. Melting of ice changes it's state of matter from solid to liquid, i.e, water. And when we

boil this water, it's state of matter changes from liquid to gas, i.e, steam. And when we condense this steam, it forms water.

Therefore, we conclude that  ice - water - steam are the three different states of a substance and not different substances. All these change of states are due to different temperatures applied.

ice  on heating  ---> (melts to) water on further heating  ----> (by evaporation) gas

Gas by condensation  ---->water on freezing  ----> ice.
