1) Gases are easily compressed and expand to fill their container due to the empty space between particles and their ability to move around. 2) The behavior of gases is described by gas laws relating pressure, volume, temperature, and amount of gas. These include Boyle's law, Charles's law, Gay-Lussac's law, Dalton's law of partial pressures, and Graham's law. 3) The ideal gas law combines these relationships and allows for calculations involving gases assuming they behave ideally. Real gases deviate from ideal behavior at high pressures and low temperatures.
