In theory, any chemical substance can achieve a gaseous state with extreme heat and/or lack of pressure. Simple table salt, for example, has a boiling temperature of nearly 2600 degrees F. Pure gold has a boiling temperature of almost 5100 degrees F. Steel, which is an alloy of iron and carbon, has a boiling temperature of 5400 degrees F. Uranium, the most massive naturally occurring element, has a boiling temperature of 6900 degrees F.
because the they need Very HIGH TEMPERATURE TO CHANGE STATE...and we cannot supply that very high temperature
The three elements that exist in the gaseous state at room temperature are helium, nitrogen, and oxygen.
No, liquid is a state of matter, not a substance itself. Substances can exist in liquid state, but liquids can be broken down into simpler substances through physical or chemical processes.
Some substances that are gaseous below 0 degrees Celsius include oxygen, nitrogen, helium, hydrogen, and carbon dioxide at certain pressures. These gases are commonly found in their gaseous state in everyday conditions even at below 0 degrees Celsius.
Just an historical legacy. Water is dihydrogen monoxide but it is always called water. Steam, water vapour are just common words that have been adopted into science. Technically, gasses cannot be seen. So if you can see the steam or vapour then it is not a gas but has already started to condense.
Yes
The physical state that cannot exist in a solution is solid. This can be either liquid or gaseous states but not in solid form.
The term gas is limited to those substances that exist in the gaseous state at room temperature and pressure. This means they have low density, take the shape of their container, and have molecules that are far apart. Gases can be compressed and expand to fill their container.

Carbon dioxide, for example, can exist in a solid state (commonly known as "dry ice") and if heated, it turns into a gas, without going through the liquid state. However, that does not mean that carbon dioxide cannot form a liquid under any circumstances. For every chemical, there is what chemists call a "phase diagram" which shows the different phases (solid, liquid, and gas) which exist under different combinations of temperature and pressure (pressure normally refers to air pressure, although other kinds are possible). Almost any chemical is capable of forming any phase under the right combination of temperature and pressure. The only exception is helium, which has no solid phase. It can be a gas or a (very cold) liquid, but not a solid. That is because helium is the most inert of all inert elements, and it has extremely little inter-atomic attraction, which is insufficient to form a solid phase even at the coldest possible temperature (absolute zero, in degrees Kelvin). The assertion in your question that some substance cannot exist in both the liquid and gaseous state is not true. Any substance, if heated sufficiently, will become a gas. Some substances require higher temperatures than others, of course.
Vapors and gases differ in their physical states and how they are formed. Vapors are substances in a gaseous state that are typically created from liquids or solids at a specific temperature and pressure, while gases exist naturally in a gaseous state. These differences can be distinguished by their origins and conditions under which they exist.
The three elements that exist in the gaseous state at room temperature are helium, nitrogen, and oxygen.
Water can exist in a solid state as ice, a liquid state as water, and a gaseous state as water vapor.
Carbon dioxide exists in the gaseous state on Earth's surface. It can also exist as a solid (dry ice) at very low temperatures or as a liquid at high pressures and low temperatures.
No, liquid is a state of matter, not a substance itself. Substances can exist in liquid state, but liquids can be broken down into simpler substances through physical or chemical processes.
In the gaseous state, acetone is considered a gas. The term "vapor" is typically used to describe the gaseous state of substances that are normally in a solid or liquid state at room temperature, while "gas" refers to substances that are typically gaseous at room temperature.
Gas and vapor are both forms of matter that exist in a gaseous state, but they differ in their physical properties. Gas refers to a substance that is in a gaseous state at room temperature and pressure, such as oxygen or nitrogen. Vapor, on the other hand, is the gaseous form of a substance that is typically a liquid or solid at room temperature, such as water vapor or gasoline vapor. In summary, gas is a general term for substances in a gaseous state, while vapor specifically refers to the gaseous form of a substance that is usually a liquid or solid.
