Some substance cannot exist in the gaseous state other cannot exist in the liquid state and some cannot exist in the both liquid and gaseous state why?

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.

What is the gaseous form of a substance which exist as a liquid at room temperature known as?
water is the substance
In what three states does water exist?
Water exists in liquid, (water); solid, (ice); and gaseous (steam) form.
Which phases of a substance can exist when the pressure is less than the pressure of the triple point?
liquid & vapor
What is a substance's critical point?
the temperature and pressure where the liquid state no longer exist is called the critical point
Can methane be a gas at -161.5c as it's boiling point?
Indeed it can. At the boiling point liquid methane is in equilbrium with gaseous methane, so both exist simultaneously.
Which is the only planet where the same substance can exist in gaseous and liquid and solid form?
earth is the only planet where the same substance can exist in gaseous , liquid , and solid form
What is the gaseous form of a substance which exist as a liquid at room temperature known as?
water is the substance
The triple point of a substance is the temperature and pressure conditions at which?
... the substance can exist in the solid, liquid, and gaseous phases all at the same time.
What is the chemical difference between the gaseous and liquid state of the same substance?
Any chemical difference exist.
What physical state cannot exists in a solution?
The physical state that cannot exist in a solution is solid. This can be either liquid or gaseous states but not in solid form.
Why some substance cannot exist in gaseous state?
because the they need Very HIGH TEMPERATURE TO CHANGE STATE...and we cannot supply that very high temperature
What is a physical form in which the substance can exist?
There are several physical forms in which a substance can exist. The common ones on earth are solid, liquid and gas, although some substances cannot exist as all three.A solid, liquid, gas or plasma.
Do all substances exist in a solid liquid or gaseous state?
Yes
Can and does francium exist in other forms?
Francium can be solid, liquid or gaseous.
What point is the temperature at which a gas turn to a liquid?
It depends completely on what specific gas you are talking about. Pretty much any chemical compound can exist in a gaseous form, and will evaporate at a boiling point different to any other compound. For example, water in its gaseous form reverts to a liquid at about 99 degrees Celsius, oxygen becomes a liquid at under -200 degrees Celsius. The point at which the substance reverts to a liquid form is also dependant on the pressure. To sum up, your question cannot be answered without knowing specifically what substance you are talking about. You need to be much more specific
Elements and substances can exist in these forms of matter?
Solid, liquid, gaseous and plasma.
Can ice and boiling water exist at same temperature?
Yes. In fact, there is a specific combination of pressure and temperature where the solid, liquid, and gaseous phases can co-exist. Do some reading on "triple point".Yes.
