An ideal gas differs from a real gas in that the particles are assumed to be point masses, that is, particles that have a mass but occupy no volume. The enormous number of molecules in even a small volume of a dilute gas produces not complication, as might be expected, but rather simplification. The temperature, pressure, and volume of a gas are linked to each other. Gases have different properties, just as solids and liquids do, and we use them for different purposes. Students will understand that the kinetic theory of matter states that, the atoms that make up all forms of matter solids, liquids and gases are always in motion.
