Types Of Gases. There are many Types Of Gases. Gas is one of the four basic states of matter. The other three are plasma, liquid, and solid. There are so many types of gases that are usually categorized as bulk gases. Some of the most common ones include; Propylene, Nitrous Oxide, Nitrogen, Oxygen, Carbon Dioxide, Helium, Hydrogen, and Argon.
The atmosphere is made up of many different gases. Several gases have the ability to reflect the sun's energy radiating from the earth back to the earth as heat. The gases with this capability are known as greenhouse gases (GHGs). The main GHGs are water vapor, carbon dioxide, methane, and nitrous oxide. Without some level of GHGs in the atmosphere, the earth would be much colder than it is and life on this planet would be much different.
