Well you can prove they are the same substance by experimenting.
If you boil liquid water it turns into steam and if you then cool the steam, it turns back into liquid water.
If you cool liquid water it will freeze and turn into ice and then if you warm the ice it will melt and tun back into liquid water.
Thus the common substance in all three states is the water.
-------------------------------------------------------------
In general substance are either solid, liquid or gaseous at normal temperatures and pressures and if you heat the solids they will turn into liquid then gas and if you cool the gases they will tun into liquid and then solids.
Solid, liquid and gas are 3 of the possible states of matter (there are other states possible)
This can be justified by looking at the exact chemical nature of each. Ice water, liquid water and steam (vapors) are ALLstill chemically the same, and exist as H2O, only in different states.
The chemical analysis show that the chemical composition of the molecule is the same.
Ice, water, and steam are all examples of the three common states of matter: solid, liquid, and gas, respectively. These states are determined by the arrangement and movement of particles in a substance.
Could be in the substances themselves. i.e. they are all subject to the same processes but at different temperatures. Thus rock, at normal temperatures, is the equal of being frozen, and rock can be heated to a point where it becomes a gas. Although it is usually a compound, so the gaseous the state of its constituent compounds would be reached at different times. Of existing gases, they can certainly be frozen to a liquid state, I have never heard of one of these becoming a solid, although I believe that some asteral bodies have frozen gases laying on the ground as a sort of frost
No, steam and water have different properties. Steam is a gas, while water is a liquid. 10 pounds of steam will not push solid water in a pipe because they are different states of matter and do not interact in the same way.

Most substances can exist in any of the three states of matter, depending on their temperature. Water if the perfect example: water, steam, and ice.
Boiling is the temperature at which a substance changes from a liquid to a gas. It is not necessarily the maximum temperature a substance can reach, as some substances can be heated to higher temperatures without boiling.
The chemical analysis show that the chemical composition of the molecule is the same.
Water is a substance composed of molecules and cannot be considered an object in the traditional sense. It can exist in different states - liquid, solid (ice), or gas (steam) depending on temperature and pressure.
-- Ice -- Water -- Steam
Yes, a substance can exist in different states of matter depending on its temperature and pressure. For example, water can be found as a solid (ice), liquid (water), or gas (steam) at different temperatures and pressures.
They are in 2 different states? The 3 states - Solid/Liquid/Gas.

When a substance changes its state of matter (e.g., from solid to liquid or from liquid to gas), the volume it occupies can change significantly. Generally, changing into a state that requires more volume often involves the substance expanding. For example, when a substance changes from a solid to a liquid or a liquid to a gas, its particles gain more kinetic energy and move more freely, leading to an increase in volume. When water turns into steam (a gaseous state), it expands significantly compared to its liquid state. Conversely, when a substance changes to a state that requires less volume, it often contracts or condenses. For example, when steam condenses back into liquid water, it occupies less space. It's important to note that the behavior of a substance during state changes depends on factors such as temperature and pressure. Additionally, not all substances behave the same way during state changes. Different substances have different properties that influence how they change states and how their volumes are affected.
