gas

Physics

A state of matter in which the matter concerned occupies the whole of its container irrespective of its quantity. In an ideal gas, which obeys the gas laws exactly, the molecules themselves would have a negligible volume and negligible forces between them, and collisions between molecules would be perfectly elastic. In practice, however, the behaviour of real gases deviates from the gas laws because their molecules occupy a finite volume, there are small forces between molecules, and in polyatomic gases collisions are to a certain extent inelastic (see equation of state).

Chemical Engineering

A physical state of matter in which the molecules of a substance are free to move and which has neither a definite shape nor volume. An ideal gas behaves as if the molecules occupy a negligible volume and that the collisions between the molecules are perfectly elastic. A real gas allows for these deviations from ideal behaviour since the molecules themselves occupy a volume and there is a small amount of attractive force between them.
