<span>Liquid carbon dioxide forms only at pressures above 5.1 atm; the triple point of carbon dioxide is about 518 kPa at 56.6 C. At this temperature and pressure CO2 will exist as a solid, liquid and gas. You cannot get a liquid by cooling alone - you have to increase the pressure as shown.</span>

Answer: Minerals range in composition from pure elements and simple salts to very complex silicates with thousands of known forms. The study of minerals is called mineralogy. To be classified as a "true" mineral, a substance must be a solid and have a crystal structure.
