Substances that exist in the gaseous phase are commonly referred to as gases.

Example of gas vapor. A gas cannot co-exist with a liquid. Examples of vapor are. Gas does not a definite shape when it is observed under a microscope.

Air oxygen carbon dioxide methane etc. Gas usually contains a single thermodynamic state at room temperature. Ethylbenzene Not Detected.

Liquids like water have a defined volume but can change their shape depending upon the container. Steam is water vapor at high temperatures. A few examples of these are the Australian thorny devil the darkling beetles of the Namibian coast and the coast redwoods of the West Coast of the United States.

When ice turns directly into water vapor without first transitioning into a liquid it is referred to as sublimation In fact any solid that turns into a vapor without going through the liquid phase can be said to sublime or sublimate Ice Changing to Water Vapor There are many examples of ice to water vapor. Water vapor and air are examples of gas. When ice becomes water this process is called melting.

Vapour has a collection of particles without any definite shape when observed under a microscope. Numerous living beings use water made accessible by condensation. Ionization energy is the energy required to remove an electron from a gaseous atom or ion.

When the tanks are opened and the liquid exposed to atmospheric pressure the liquid boils off from the latent heat of the. When water becomes water vapor it is called evaporation. Examples of gas include oxygen and carbon dioxide.
