Definition of ideal gas in English: ideal gasnoun Chemistry A hypothetical gas whose molecules occupy negligible space and have no interactions, and which consequently obeys the gas laws exactly. Example sentencesExamples - An underlying premise is that an ideal gas obeys the gas laws perfectly, and its behavior may be adequately described by kinetic theory.
- However, in the case of compressed gases, the compressibility at high densities falls to a small fraction of the value predicted for the ideal gas.
- Even though no ideal gases exist, real gases, for the most part, adhere to the principles outlined above.
- For gases, the standard state is the ideal gas at standard pressure.
- In the case of an ideal gas (whose molecules do not interact) there will be no change in internal energy either so.
