b) the E=mc{eq}^2{/eq} energy if all the mass in one gallon of gasoline were turned into energy? The Internal Energy. The internal energy of a pure substance is the energy related to its activity and molecular structure. ...
Short for gasoline We stopped for gas Oil An oil is any nonpolar chemical substance that is a viscous liquid at ambient temperatures and is both hydrophobic (does not mix with water, literally "water fearing") and lipophilic (mixes with other oils, literally "fat loving"). Oils have a high...
A hydrogen fuel cell bus has three main components: the fuel cell stack, the electric motor, and the hydrogen storage tanks. The fuel cell stack is made up of individual fuel cells that combine hydrogen and oxygen to produce electricity, heat, and water as byproducts. The electric motor is...
Higher octane fuel, boasting ratings of 91 to 93 or higher, is engineered for high-performance engines with high compression ratios, turbochargers, or those specifically tuned to require premium gasoline. The History of Octane During WWI, it was discovered that you can add a chemical called ...
They work together to make the car go.Plug-in Hybrid Electric Vehicles (PHEVs): These cars also have a battery that can be charged from an outside source, along with a gasoline engine.Fuel Cell Electric Vehicles (FCEVs): These use special cells that turn hydrogen fuel into electricity. ...
There are several ways to use hydrogen for energy once it is produced. The most prominent is in fuel cells, which convert the chemical energy stored in hydrogen and oxygen into electricity. Unlike with gasoline-fueled engines, there are no harmful emissions like carbon dioxide. And unlike with...
These gains arise because the densities of petroleum products (gasoline, kerosene, diesel fuel, jet fuel, heating oil, etc.) are less than the density of crude oil they were made from. It is like making a low calorie butter or cheese from a normal butter or cheese by puffing them up ...
If you have read the article How Emergency Power Systems Work, then you also know that an alternative to gasoline-powered generators is an inverter powered by one or more deep cycle batteries. Both car batteries and deep cycle batteries are lead-acid batteries that use exactly the same ...
