Question

How will you justify that ice water and
steam are not different substances but

different states of the same substances?

wrong answers will be reported.​

Answer 1

When ice (solid state) is heated, it melts and changes to water (liquid state). When water is boiled, it is converted to steam (gaseous state). The process can be reversed upon cooling. This justifies that these are the states of a substance. In fact, all the three states are

chemically the same with the formula H²O.
