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.

2025年3月25日 · 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.

2021年3月23日 · 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.

Gas is one of the four fundamental states of matter. The others are solid, liquid, and plasma. [1] . A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).

2021年9月1日 · 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).

A list of 10 examples of gases is provided on this page. Gas is one of the fundamental states of matter along with the solid, liquid, and plasma state. Learn about gases here.

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).

2019年5月4日 · Gases at room temperature include air, chlorine, ozone, oxygen, and hydrogen. Gases have lots of space between particles and are usually clear, with a few exceptions. A gas is defined as a state of matter consisting of particles that have neither a …

2024年4月28日 · 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.

2022年2月16日 · 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...
