What is the difference between gas and vapor?
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.
What is the difference between a gas and a vapour?
A gas is a substance in a state in which it expands to fill the available space, whereas a vapor is the gaseous state of a substance that is typically a liquid or solid at room temperature. In general, gases can exist at room temperature, while vapors typically need to be heated to reach their gaseous state.
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 a substance's critical point?
A substance's critical point is the temperature and pressure at which the gas and liquid phases of the substance become indistinguishable, forming a supercritical fluid. At the critical point, the substance exhibits unique properties, such as density and viscosity, that differ from those of its gas or liquid phases.
Is triple point unique?
Yes, the triple point is a unique point on a phase diagram where a substance exists in equilibrium in all three phases (solid, liquid, gas) simultaneously. At the triple point, the temperature and pressure values are specific for that substance, making it a distinctive point.
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
The triple point of a substance is the temperature and pressure conditions at which?
the solid, liquid, and gas phases of a substance coexist in equilibrium. At the triple point, the substance can exist in all three states simultaneously. It is a unique combination of temperature and pressure for each substance.

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.
What is the difference between a gas and a vapour?
A gas is a substance in a state in which it expands to fill the available space, whereas a vapor is the gaseous state of a substance that is typically a liquid or solid at room temperature. In general, gases can exist at room temperature, while vapors typically need to be heated to reach their gaseous state.
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 state can a physical form in which a substance can exist?
A physical state in which a substance can exist depends on its temperature and pressure. Common states include solid, liquid, gas, and plasma. For example, water can exist as ice (solid), liquid water, or steam (gas) depending on its temperature and pressure.
Is water the same thing as gas?
Yes
What is the triple point temperature?
The triple point temperature is the temperature at which a substance can exist in equilibrium as a solid, liquid, and gas simultaneously. It is unique for each substance and defined by its specific pressure conditions.
Difference between vapour and gas?
A vapor is a gas, but it is at a temperature where the substance could also exist as a liquid or a solid. The easiest example is water. Water will evaporate at any temperature above 0 degrees Celsius...but if the pressure of the water vapor increases sufficiently or if the air becomes saturated, the water vapor will condense back to liquid water.
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.
