What is a substance's critical point?
the temperature and pressure where the liquid state no longer exist is called the critical point
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.
Is triple point unique?
No. Nearly every element and compound has a "triple-point", the combination of pressure and temperature which allows the solid form, the liquid form and the gaseous form to exist at once.
Why can't calcium carbonate exist in a liquid state nor in the gaseous state?
At high temperature calcium carbonate (CaCO3) is decomposed in calcium oxide (CaO) and carbon dioxide (CO2).
The term gas is limited to those substances that exist in the gaseous state at?
room temperature
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.
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
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.

What is the chemical difference between the gaseous and liquid state of the same substance?
Any chemical difference exist.
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 the condensation point of water in kelvin?
The condensation point in Kelvin is 373 Kelvin. At this temperature, the liquid and gaseous state of water exist in equilibrium.
What is a substance's critical point?
the temperature and pressure where the liquid state no longer exist is called the critical point
Nitrogen is a gas?
Yes, nitrogen exists in a gaseous form (N2) at at temperatures above its boiling point. It can also exist as a liquid at 77 K.
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
