How can ice water and steam be three states of a substance and not different substances?

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)

How will you justify that icewater and water vapours are the three states of a substance and not substances?
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.
How will we justify that ice water steam are the three state of a substance and not different substance?
The chemical analysis show that the chemical composition of the molecule is the same.
How will you justify that ice water and steam are not different substances but different states of the same 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
What is change in a substance that does not involve a change in the identity?
Then the physical characteristic of a substance change, it is called a change in state. This most commonly occurs when a substance is heated or cooled. The states that substances are solid, liquid and gas. A common example would be water: ice (solid), water (liquid), and steam (gas).
Does a change in state mean that a new substance has formed?
In a "physical change" a new substance is not created. In a "chemical change" a new substance is created. This applies to changes in states of matter. For example, ice, water, and steam are all the same substance, even though they exist in three different states. The elements of which they are comprised do not change. Sometimes you may be able to precipitate elements out of a substance through a phase change. In a mixture of alcohol and water you can fairly quickly boil out the alcohol.

Name a substance that can exit in all three stats of matter?
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.
What is the fractional distilation?
In distillation you boil off the substance you want ... then re-condense it. In fractional distillation you boil up a mixture of original substance ... and tap off the "steam" (the vapor) at various levels (thus different temperatures) and so you get different substances at each tap. It is most commonly used for crude oil to get many products.

What are the different states of matter for water called?
-- Ice -- Water -- Steam
What is the difference between a substance and an element?
A substance is any matter, any material which has mass and occupies space. As far as a specific substance, a material has a specific constitution.An element is a pure substance which cannot be broken down into (or synthesized by) other substances.For example, water is a substance, but water itself is the result of the union of two other elements, hydrogen and oxygen.An element cannot be made by joining other substances together (example, gold).

Which Substances change directly from steam to gas?
Steam is gas. Gaseous water to be exact.
What is the main difference between water and steam?
They are in 2 different states? The 3 states - Solid/Liquid/Gas.
it becomes harder to change into a state that needs more volume?
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.
