1. What is in Gasoline? Gasoline is produced from a dark substance extracted from miles beneath the surface‚ called crude oil or petroleum. Millions of years ago‚ crude oil was created from fossil fuels of dead animals and plants that sank into the ocean’s bottom underneath rocks‚ dirt‚ and dust. Over time‚ the seclusion of corpses caused heat and pressure to increase instigating the bodies to decompose; and due to lack of oxygen‚ the remains formed mixture of chemical organic compounds made of hydrogen

is the effect of gasoline fumes on bean plant growth? Hypothesis: If the bean plants are exposed in the presence of gasoline fumes for a longer period of time‚ then the plants will die more quickly. Procedures: 1. Place ten bean plants in each of five Rubbermaid clear plastic containers. 2. Let the bean plants sit for one week without being manipulated. 3. Leave the first container alone without manipulation. 4. Expose the second container to gasoline fumes for a fifteen

White Every spring‚ around Memorial Day‚ we watch in frustration as gas prices rise. Every year we say that we are going to do something about it but most of us don’t. Instead‚ we swear and complain as we pump gas that costs nearly four dollars a gallon. Surely by now most Americans are considering hybrids or electric powered cars for their

Consumer availability of electric‚ propane and gasohol products for personal vehicle use began in the 1970 ’s. Currently‚ three main types of vehicles operating on alternative fuels are readily available: · Vehicles contain a single fuel tank capable of operating on alcohol‚ gasoline or a combination of both (gasohol)

allocates indirect costs to the three different grades of gasoline based on the average amount of gasoline sold from each grade. On the other hand‚ the defendant‚ BuyGasCo‚ utilizes an approach in which the indirect costs are allocated using a simple average approach‚ which allocates the same cost to each grade‚ regardless of volume sold. The difference in approaches provides for a difference in indirect costs for each grade of gasoline. This poses a problem because the Florida Motor Fuel Marketing

Antiknock agent An antiknock agent is a gasoline additive used to reduce engine knocking and increase the fuel’s octane rating by raising the temperature and pressure at which ignition occurs. The mixture known as gasoline‚ when used in high compression internal combustion engines‚ has a tendency to ignite early before the correctly timed spark occurs (pre-ignition ordetonation) causing a damaging "engine knocking" (also called "pinging" or "pinking") noise. Research[edit] Early research into this

to bear this out: as of 1996‚ leaded gasoline comprised 93 percent of all gasoline in Africa and 94 percent in the Middle East. The numbers were 30 and 35 percent respectively in Asia and Latin America (Hitt‚ Ireland & Hoskisson ‚ 2011). Technological – Technological considerations could have a great impact on Great Lakes when and if the countries in which it does business take the plunge and move from leaded to unleaded gasoline. Since leaded gasoline use was banned in the United States and

By knowing the qualitative and quantitative composition of the gasolines‚ the content of n-paraffin‚ isoparaffin‚ aromatic‚ naphthene‚ and olefin (PIANO) groups of hydrocarbons as well as of oxyorganic compounds (alcohols and ethers) used to raise the octane number can be determined.

A more efficient engine means that a car will burn less fuel to travel the same distance reducing pollutants. This is good for car owners too because they do not need to buy so much fuel. Even a very efficient engine will still

Vehicles that are capable to use e85 are known as flex fuel vehicles‚ because e85 is a blend of anywhere between fifty and eighty-five percent ethanol the vehicle’s engine control unit (ecu)‚ or a computer needs to be able to gauge how much ethanol and how much gasoline is running through the engine.
