Water can exist in three states of matter. Imagine examining the changes of state from solid to liquid to gas by adding to ice.
loris [4]

<u>Answer:</u>

<em>We know water can exist in all three states be it solid or liquid or gas the only difference between the three states is the temperature at which they exist. </em>

<u>Explanation:</u>

When the temperature moves towards colder region the state of water changes to solid while when the temperature moves to water region the state of water changes to gas.

This little experiment can be done with the help of ice at room temperature. The more ice is applied to water it will turn to ice but removal of eyes in room temperature. And will make it turn to water and complete removal of eyes with application of heat would make it into vapour.
