Which substance in the gaseous state should be calleda vapour?
A substance in the gaseous state that is typically a liquid or solid at room temperature can be referred to as a vapor. Examples include water vapor or steam, which is the gaseous state of water.
What are the three elements that exist in the gaseous state at room temperature?
The three elements that exist in the gaseous state at room temperature are helium, nitrogen, and oxygen.
Which state is a vapour?
A vapor is not a state of matter; it is a gaseous form of a substance that is typically in the gas phase at a temperature below its critical point.
Is it correct to regard gaseous state of carbon dioxide as vapour why?
Yes, it is correct to regard the gaseous state of carbon dioxide (CO2) as vapor because it is a substance that can exist in both solid and liquid states under certain conditions. In its gaseous form at standard temperature and pressure, CO2 is typically considered a vapor since it can condense into a liquid or solid (dry ice) when pressure and temperature are adjusted. Additionally, the term "vapor" generally refers to the gaseous state of a substance that is normally found in solid or liquid form at room temperature.
Is there a difference between the gaseous and liquid state of the same substance?
yes
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.
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.
Which substance in the gaseous state should be calleda vapour?
A substance in the gaseous state that is typically a liquid or solid at room temperature can be referred to as a vapor. Examples include water vapor or steam, which is the gaseous state of water.
Does molten state mean gaseous state?
No, molten state refers to a substance that has been heated to the point of becoming liquid, while the gaseous state refers to a substance in which its particles are free to move without a definite shape or volume. In the molten state, the substance retains its liquid form, whereas in the gaseous state, the substance exists as a gas.
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.
If the volume of a substance in the gaseous state is 1000 times the volume of that substance in the liquid state how much space would 18mLof that substance in the liquid state take up if it evaporated?
If 18 mL of the substance in the liquid state evaporated and its volume in the gaseous state is 1000 times greater, it would occupy a volume of 18 mL × 1000 = 18,000 mL, or 18 liters, in the gaseous state.
What is the energy needed for a substance to change from a liquid state to a gaseous state?
thermol
What is the substance of boiling point?
The boiling point of a substance is the temperature at which it changes from liquid state to gaseous or vapor state.
In the volume of a substance in the gaseous state is 1000 times the volume of that substance in the liquid state how much space would ml of that substance in the liquid state take up if it evaporate?
If the volume of the substance in the gaseous state is 1000 times the volume of the substance in the liquid state, this means that 1 ml of the substance in the liquid state would occupy 0.001 ml when it evaporates into a gas.
What is the gaseous state of a substance that is normally a liquid or solid?
Vapour
What are the three elements that exist in the gaseous state at room temperature?
The three elements that exist in the gaseous state at room temperature are helium, nitrogen, and oxygen.
