Question

Ice, water, and stream are three state of substance and not different substance why?

Answer 1

Ice, water and steam are the three states of the same substance because they consist of same constituent elements (i.e., hydrogen and oxygen), same molecules and same chemical properties. Only the arrangement of the molecules differ in these three states. In ice, the molecules are densely packed, while in water, the molecules are somewhat loosely packed. In steam, the molecules are far off from each other. Moreover, we can change water into steam as well as ice and again get back water from them.
