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.

Full Answer

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:

    Why are gases easily compressed?

    A:

    Gases can be compressed easily because there is a large amount of space between the individual molecules, which are very active and move around at high speed. When gas is compressed, the particles are forced much closer together, allowing a huge amount of particles to fit in a small space.

  • Q:

    Why can gases be compressed?

    A:

    Gases can be compressed because each gas particle has relatively vast amounts of room between it and all other gas particles the majority of the time. Thus, compression, which is essentially forcing the gas particles closer together, has a great deal of space to reduce. This contrasts with liquids and solids, which have particles in constant contact with one another, and thus little room to compress.

  • 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.
