Compressibility factor is significant because it determines how far a gas is from it's ideal state, based on various factors. The compressibility factor is determined by the pressure, volume, temperature and number of moles in the gas.
Continue ReadingA gas in its ideal state has a compressibility factor of exactly 1 unit. Real gases often deviate from an ideal compressibility factor due to variations in temperature and pressure. As pressure increases, the compressibility factor of a gas also increases. As temperature increases the compressibility factor of a gas decreases. Factors that have the highest net effect on the compressibility factor of a gas are high pressure states and low temperatures.
