Ideal gas assumptions

  1. Aug 29, 2009 #1
    I was wondering if it assumed the gas could not turn into a liquid?

    You need to be a bit more "explanatory" with your question. For example, it is clearly stated as part of the ideal gas law assumption that the gas particles do not interact with one another other than making elastic collisions. Did you understand this part of the ideal gas law?

    Now think about what a "solid" is. A "solid", by definition, means that the particle form BONDS with each other to be able to maintain a rigid shape.

    Does that answer your question?

    Nah, yeah that is what I thought. Just was not sure. So does that mean for a monochromatic gas that is near the temperature at which it turns into a liquid, the ideal gas law is not so good?

    The ideal gas law is most accurate for monoatomic gases at high temperatures and low pressures. Although, I assume, depending on the necessary accuracy of the measurements and the specifics of the experiment, one could still use the Ideal Gas Law for temperatures near condensation.
