  • Thermodynamic Properties of Propane. III. A Reference Equation . . . - NIST
    Propane has a very low reduced triple point temperature (Ttp Tc) of 0 23 that makes it a prime candidate for corresponding states applications There are only a handful of other fluids, such as 1-butene, that have slightly lower values
  • Propane - Wikipedia
    Propane is a colorless, odorless gas Ethyl mercaptan is added as a safety precaution as an odorizer, [23] and is commonly called a "rotten egg" smell [24] At normal pressure it liquifies below its boiling point at −42 °C and solidifies below its melting point at −187 7 °C Propane crystallizes in the space group P2 1 n [25][26] The low space-filling of 58 5% (at 90 K), due to the bad

  • How Do Temperature Changes Affect Propane? | LP Propane
    Thermal Expansion and Contraction Propane expands with temperature increase This may raise the internal pressure in a tank and, if not well managed, poses a safety risk On the other hand, when the temperature lowers, propane contracts, thereby reducing pressure and may be inapplicable
  • PROPANE - thermopedia. com
