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

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 you justify that ice and water and water vapour are the states of a substance and not substance?
Ice, water, and water vapor are all different states of the same substance, which is H2O or water molecules. These states represent different configurations of the molecules due to changes in temperature and pressure. They can interconvert between each other through the processes of freezing, melting, evaporation, and condensation.
Why do some substance float on top of the other substances when layered?
Substances float on top of others based on their densities. When two or more substances are layered, the one with the lower density will float above the one with a higher density. This is governed by Archimedes' principle, which states that an object will float if it displaces a volume of fluid equal to its weight. Consequently, substances with different densities will stratify, with less dense substances on top.
Do all substances change states at the same temperatures?
No, substances do not change states at the same temperatures. Each substance has its own unique melting and boiling points, which depend on its molecular structure and intermolecular forces. For example, water freezes at 0°C and boils at 100°C, while other substances like ethanol and mercury have different freezing and boiling points. Thus, state changes occur at specific temperatures for each material.
How do substances move from one state to another?
Substances can change states through processes such as melting, freezing, evaporation, condensation, or sublimation. These changes occur when the temperature or pressure of the substance is altered, causing the particles to either gain or lose energy and rearrange themselves into a different state.

What is the density of a substance determine?
It seems that the phrase you are looking for is "physical property". Density depends on several factors, such as: is the substance a solid, liquid or gas (the same substance will have vastly different densities at different states, but density is still a physical property of that substance); what temperature is it being measured at (most substances expand and become slightly less dense when heated); among others.

When a substance changes states at different temperature and pressure this is called?
pasterisation
When two substances react chemically to produce a new substance what is TRUE of the mass of the two substances compared to the mass of the new substance?
The mass of the two substances before the reaction is equal to the mass of the new substance after the reaction. This is in accordance with the law of conservation of mass, which states that matter can neither be created nor destroyed in a chemical reaction, only rearranged.
What are the different characteristic of matter?
Matter can be classified as a pure substance or a mixture. Pure substances are made of only one type of atom or molecule, while mixtures contain two or more different substances physically combined. Matter also has properties like mass, volume, and density, and can exist in different states - solid, liquid, gas, or plasma - depending on the arrangement of its particles.
Is water the only substance on earth?
AnswerCommonly exists in all of its different states
What does the state of a substance depend on?
Typically pressure and temperature determine whether a substance is gas, liquid or solid. Some substances however are not easily forced into some of the states, and that is determined by by individual molecular qualities.
The more-abundant substance in a solution?
in any solution the substanse with the greatest quanity is the
What are some things that have melting points?
All substances have a melting point.Water, for example, has a melting point. It is simply the temperature at which a substance changes states to a liquid.
How did the confederacy justify its secession?
the united states had been formed by a voluntary joining of states
