Ideal Gas

An enormous number of very tiny particles separated by relatively large distances. The particles have no internal structure, are indestructible, do not interact with each other except when they collide, and all collisions are elastic.

Ideal gases have molecules with negligible size, and the average molar kinetic energy of an ideal gas depends only on its temperature. Most gases behave ideally at sufficiently low pressures.
