The density of liquid propane at 25 °C (77 °F) is 0.493 g/cm 3, which is equivalent to 4.11 pounds per U.S. liquid gallon or 493 g/L. Propane expands at 1.5% per 10 °F. Thus, liquid propane has a density of approximately 4.2 pounds per gallon (504 g/L) at 60 °F (15.6 °C). [30] As the density of propane changes with temperature, this fact ...
The pressure at which LPG becomes liquid, called its vapour pressure, likewise varies depending on composition and temperature; for example, it is approximately 220 kilopascals (32 psi) for pure butane at 20 °C (68 °F), and approximately 2,200 kilopascals (320 psi) for pure propane at 55 °C (131 °F).

[56] [57] Autogas use by car drivers can help the United States to reduce dependence on foreign oil as 90% of all U.S. Autogas is produced in the U.S. [58] [59] In 2005, a provision was enacted that placed a 50-cent per gallon tax credit on propane autogas as part of H.R. 4853, making it $1 per gallon cheaper than petrol on average. The ...
Coupons can be used to research the price sensitivity of different groups of buyers (by sending out coupons with different dollar values to different groups). Time, location and sizes (e.g. five pound vs. 20 pound bag) [12] affect prices; coupons are part of the marketing mix. [13] So is knowing about the customer. [14] [12]
The emissions from ships have generally been controlled by the following sulfur caps on any fuel oil used on board: 3.50% on and after 1 January 2012 and 0.50% on and after 1 January 2020. [25] Further removal of sulfur translates to additional energy and capital costs [ 26 ] and can impact fuel price and availability.
