Q:

What are types of gases?

A:

A type of gas is a classification in which a gas falls under that describes its properties. Gases can be classified as oxidizers, inert gases and flammable gases.

Oxidizing gases are not flammable gases but contribute to a combustion reaction. They should not be used in combination with fats or oils. Inert gases do not react with other substances and do not participate in combustion reactions. When an inert gas is emptied into a room or space, it reduces the amount of oxygen present and limits the process of combustion. This principle is applied in extinguishing systems. Flammable gases combine with air or oxygen and burn or explode.

A gas is one of the three states of matter, including solids and liquids. Gas particles contain large amounts of energy but are less organized than particles of other matter states. They are spread out over a greater distance and move more randomly. Gas has the ability to expand or compress to fill a container. This is done with a manipulation of the pressure of the gas as well as changing the temperature. Gases move from areas of high pressure to areas of lower pressure. If a gas is a liquid at room temperature, it is referred to as a vapor.

  • Q:

    What are the properties of an ideal gas?

    A:

    Ideal gases are hypothetical substances studied by scientists and students to simplify intermolecular forces. Ideal gases are point masses that constantly move in a random, straight-line nature. The behavior of ideal gases, meaning the relationship of pressure (P), temperature (T) and volume (V) is summarized as PV=nRT, where "n" is the number of moles of gas. This equation for ideal gases will always equal one.

  • Q:

    What are noble gases?

    A:

    The noble gases are a group of seven elements on the Periodic Table of Elements. Together they make up Group 18 on the table and include (in increasing atomic number) helium, neon, argon, krypton, xenon, radon and element 118, which has been temporarily named ununoctium. All noble gases display similar properties under standard conditions. They are colorless, tasteless, odorless and non-flammable.
