Liquids and gases both have the property of having no fixed shape, and change their shape depending upon their surrpoundings. Gases, unlike liquids, also have no fixed volume, and readily expand or contract.

∙ 11y agoAlthough liquids and gases both share the common characteristics of fluids, they have many distinctive characteristics of their own. A liquid is difficult to compress and, for many purposes, may be regarded as incompressible. A given mass of liquid occupies a fixed volume, irrespective of the size or shape of its container, and a free surface is formed if the volume of the container is greater than that of the liquid.
A gas is comparatively easy to compress. Changes of volume with pressure are large, cannot normally be neglected and are related to changes of temperature. A given mass of gas has no fixed volume and will expand continuously unless restrained by a containing vessel. It will completely fill any vessel in which it is placed and, therefore, does not form a free surface.

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.
What is the difference between the atmosphere of earth and space?
An atmosphere implies the presence of a gaseous substance (such as air, in the earth's atmosphere, which is primarily made up of nitrogen and oxygen). Space is defined as the absence of atmosphere (as pure space consists of no solid, liquid or gaseous substance).
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.
When a substance changes from one state to another do the chemical properties change?
From solid to liquid, from liquid to gaseous, from gaseous to liquid, from liquid to solid, and in sublimation from solid to gaseous or the reverse, chemical properties do not change.
What is the general term used to identify transitions between the solid liquid and gaseous forms of a substance?
phase change
