This is a list of gases at standard conditions, which means substances that boil or sublime at or below 25 °C (77 °F) and 1 atm pressure and are reasonably stable.

Mar 23, 2021 · Examples of gases include air, water vapor, and helium. A gas is a state of matter that has no fixed volume or shape. In other words, a gas takes the shape and volume of its container.

Mar 25, 2025 · gas, one of the three fundamental states of matter, with distinctly different properties from the liquid and solid states. The remarkable feature of gases is that they appear to have no structure at all.

Gas is one of the four fundamental states of matter. The others are solid, liquid, and plasma. [1][better source needed] A pure gas is made up of individual atoms (e.g. a noble gas like neon) or molecules of either a single type of atom (elements such as oxygen) or from different atoms (compounds such as carbon dioxide).

Sep 1, 2021 · Here is a list of 10 gases and their uses: The monatomic gases consists of single atoms. These gases form from the noble gases, such as helium, neon, krypton, argon, and radon. Other elements typically form diatomic gases, such as oxygen, nitrogen, and hydrogen. A few pure elements form triatomic gases, such as ozone (O 3).

Gas is a type of matter that has no defined shape or volume. Gases can be made up of a single element, such as hydrogen gas (H 2), a compound, such as carbon dioxide (CO 2), or a mixture of several gases, such as air. The gaseous state is one of the four fundamental states of matter (along with the solid state, the liquid state and plasma).

Gases have the lowest density of the three, are highly compressible, and fill their containers completely. Elements that exist as gases at room temperature and pressure are clustered on the right side of the periodic table; they occur as either monatomic gases (the noble gases) or diatomic molecules (some halogens, N₂, O₂).

Apr 28, 2024 · In this chapter, we explore the relationships among pressure, temperature, volume, and the amount of gases. You will learn how to use these relationships to describe the physical behavior of a sample of both a pure gaseous substance and mixtures of gases.

Feb 16, 2022 · Gas is a state of matter that has no fixed shape and no fixed volume. Gases have a lower density than other states of matter, such as solids and liquids. There is a great...

Aug 25, 2021 · Many elements exist as gases at standard temperature and pressure, while other elements and compounds can become gases under certain circumstances. Take a look at several examples of gas in different contexts, organized by types of gases.
