Webb25 feb. 2024 · O2 and N2 molecules are only slightly different in molecular size but both are very small. O2 does have a greater molecular weight (32) than N2 (28), but O2 is actually smaller in size. Thus, O2 fits through the relatively tight passage ways between polymer chains in the rubber more easily than does N2. Webb10 aug. 2024 · Since the diameter of each gas molecule is much less than this (4 x 10 -8 cm for air, for example), there is a great deal of space between molecules. To put it into proportion, if gas molecules were grains of sand, at …

On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel ); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. [2] Visa mer Gasoline or petrol (CW except Canada; /ˈpɛtrəl/) (see § Etymology) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as Visa mer The first internal combustion engines suitable for use in transportation applications, so-called Otto engines, were developed in Germany during the last quarter of the 19th century. The fuel for these early engines was a relatively volatile Visa mer Spark-ignition engines are designed to burn gasoline in a controlled process called deflagration. However, the unburned mixture may autoignite by pressure and heat alone, rather than igniting from the spark plug at exactly the right time, causing a rapid pressure rise … Visa mer "Gasoline" (often shortened to "gas" and differentiated from avgas in the names "motor gas" or "mogas") is a North American word that denotes fuel for automobiles.
