  2. Propane - Wikipedia

    en.wikipedia.org/wiki/Propane

    The enthalpy of combustion of propane gas where products do not return to standard state, for example where the hot gases including water vapor exit a chimney, (known as lower heating value) is −2043.455 kJ/mol. [29] The lower heat value is the amount of heat available from burning the substance where the combustion products are vented to the ...

    Propane does not have health effects other than the danger of frostbite or asphyxiation. The National Propane Gas Association has a generic MSDS available online here. (Issued 1996) MSDS from Suburban Propane, L.P dated 5/2013 in the SDSdata.org database

  4. Ideal gas law - Wikipedia

    en.wikipedia.org/wiki/Ideal_gas_law

    Isotherms of an ideal gas for different temperatures. The curved lines are rectangular hyperbolae of the form y = a/x. They represent the relationship between pressure (on the vertical axis) and volume (on the horizontal axis) for an ideal gas at different temperatures: lines that are farther away from the origin (that is, lines that are nearer to the top right-hand corner of the diagram ...

  5. Liquefied petroleum gas - Wikipedia

    en.wikipedia.org/wiki/Liquefied_petroleum_gas

    LPG is composed mainly of propane and butane, while natural gas is composed of the lighter methane and ethane. LPG, vaporised and at atmospheric pressure, has a higher calorific value (46 MJ/m 3 equivalent to 12.8 kWh/m 3 ) than natural gas (methane) (38 MJ/m 3 equivalent to 10.6 kWh/m 3 ), which means that LPG cannot simply be substituted for ...

  7. Alcohol (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Alcohol_(chemistry)

    The word's meaning became restricted to "spirit of wine" (the chemical known today as ethanol) in the 18th century and was extended to the class of substances so-called as "alcohols" in modern chemistry after 1850. [16] The term ethanol was invented in 1892, blending "ethane" with the "-ol" ending of "alcohol", which was generalized as a libfix ...

  9. Propylene - Wikipedia

    en.wikipedia.org/wiki/Propylene

    Propylene, also known as propene, is an unsaturated organic compound with the chemical formula CH 3 CH=CH 2. It has one double bond, and is the second simplest member of the alkene class of hydrocarbons. It is a colorless gas with a faint petroleum-like odor. [4]
