Document Summary
Matter (anything that takes up space and has a mass) generally exists in the following states: solids, liquids, and gases. Solids consist of particles that are packed closely together (generally due to stronger electrostatic forces of attraction), and which also have a low energy state (only vibrational motion/energy). Therefore the volume of a container is the same as the volume of a given gas. The kinetic molecular theory refers to ideal gases, which do not actually exist. However, the behaviour of real gases does not differ that much from ideal gases, thus it is a good approximation (for calculation simplification purposes) to treat all gases as ideal gases. There are several experimentally determined relationships between several variables related to gases (pressure, temperature, volume, and amount (mole)). These relationships are concisely summarized as the gas laws: Boyle"s law - pressure is inversely proportional to volume or. P1v1 = p2v2, keeping both temperature and amount (mole) constant.
