What is the process in which a substance changes from a gaseous state to the liquid state is?
condensation =)
What is the difference between water vapor and oxygen?
The word vapour is used to describe those gases that usually exist as liquid at room temperature . Water particles in gaseous state are called vapours . Oxygen at room temperature exists as gas particles .
What are the Changes of state?
There are three main states that a substance can exist as: solid, liquid and gas. The transition between these states occur when a substance is heated or cooled past their freezing/melting or boiling/condensing points. Solid -> Liquid = Melting Liquid -> Gas = Boiling Gas -> Liquid = Condensing Liquid -> Solid = Freezing
What two processes change water into a gaseous state?
In evaporation, a liquid such as water changes to a gaseous state. In sublimation, a solid such as ice changes driectly to a gas or vapor without going through a liquid state.
Substances expand when heated because the molecules?
According to the particle theory, particles move faster and further apart when exposed to higher temperatures. When a substance is heated, its particles acquire thermal energy. These energetic particles--which are constantly vibrating, even in solid form--become very excited, and move around much more, therefore requiring more space. The substance begins to increase in volume, creating larger spaces in between its molecules to accommodate the high-energy movement. This can also cause a change in state. Particles of substance in a solid state: vibrating slightly, densely packed together, little space between molecules. Compare to, Particles of substance in a gaseous state: vibrating excitedly, larger spaces in between molecules, easily compressible (due to empty spaces) If you were to cool a substance in gaseous form, the particles would begin to lose their thermal energy, and eventually change into a liquid state.
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.
Is there a chemical difference between the gaseous state and liquid state of a substance?
Phase has nothing to do with chemical composition.
Can a mixture of liquid and gaseous water be considered a pure substance?
Yes it can, the only difference between liquid and gaseous water is it's physical form, not it's chemical composition.
Can a liquid substance diffuse in another liquid substance a gaseous in liquid a gaseous in gaseous?
Yes, all of them.
Is there a chemical difference between the gauseos and liquid state of the same substance?
There is no chemical difference, the only difference is the speed in which the molecules of the substances move. Slower molecules can be solid or liquid and very high speed molecules can be gas.
What is the gaseous form of a substance which exist as a liquid at room temperature known as?
The gaseous form of a substance that exists as a liquid at room temperature is known as vapor.
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.
Compare the magnitudes of dipole-dipole forces between particles of a substance in the liquid state to the gaseous state?
In a liquid forces are stronger.
Difference between evaporation and vaporization?
Vaporization is the conversion of a solid or liquid into a gaseous state. Evaporation is a type of vaporization, where liquid is converted to a gaseous state where the environment is not saturated.
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
Does liquid oxygen react with gaseous oxygen?
No. Liquid oxygen and gaseous oxygen are the same substance, just in different states.
