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.
The most common example of a gas is air (the air we breathe is a gas). It can also be considered as a mixture of many gases such as nitrogen, oxygen and carbon dioxide. Some examples of gases are listed below.
Example Gases. Here is a list of 10 gases and their uses: Oxygen (O 2): medical use, welding. Nitrogen (N 2): fire suppression, provides an inert atmosphere. Helium (He): balloons, medical equipment. Argon (Ar): welding, provides an inert atmosphere for materials. Carbon dioxide (CO 2): carbonated soft drinks. Acetylene (C 2 H 2): welding.
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. They have neither a definite size nor shape, whereas ordinary solids have both a definite size.
Examples of Gases. Whether or not a substance is a gas depends on its temperature and pressure. Examples of gases at standard temperature and pressure include: air (a mixture of gases) chlorine at room temperature and pressure. ozone. oxygen. hydrogen. water vapor or steam. List of the Elemental Gases.
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.
Elemental gases. The only chemical elements that are stable diatomic homonuclear molecular gases at STP are hydrogen (H 2), nitrogen (N 2), oxygen (O 2), and two halogens: fluorine (F 2) and chlorine (Cl 2).
