The Effect of Gasoline Fumes on plants Introduction: This science fair project was conducted to study the effect of gasoline fumes on plants. The testing was done by placing plants beside a gasoline-filled container for different periods of time and temperatures. Hypothesis: Gasoline fumes cause plants to die - the longer the exposure to the fumes‚ the quicker the plants will die. Our second hypothesis is that exposure to fumes‚ at higher environmental temperatures‚ will result in quicker

What 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

STOICHIOMETRY OF GASOLINE. AN INTRODUCTION The internal combustion engines burn fuel to create kinetic energy. The burning of fuel is basically the reaction of fuel with oxygen in the air to form water and Carbon dioxide as the major end product . The amount of oxygen present in the cylinder is the limiting factor for the amount of fuel that can be burnt that is to say it determines the level of burning in our combustion engine. If there’s too much fuel present‚ not all fuel will be burnt and un-burnt

assortment of sectors including agriculture‚ healthcare‚ workforce‚ and transportation. The transportation sector involves the taxation of gasoline. Gasoline balances on a positive and negative line. On one hand‚ it provides transportation for the majority of citizens and companies in North America. However‚ Menkes and Fawcett explain‚ “octane enhancing constituents of gasoline pose a number of health hazards including metallic (lead‚ manganese)‚ aromatic (e.g.‚ benzene)‚ and oxygenated additives in both industrialized

experiment was composed to show the effects that different colors of light have on plant growth. We separated our plants into different boxes and then covered the openings with colored cellophane. We conducted this experiment for approximately two weeks. Out of the colors blue‚ green‚ red‚ and yellow‚ the plant behind the blue cellophane grew the most. Research Problem What effects does different color light have on plant growth? Hypothesis The plants will grow taller under the red and blue

that contributes to the pollution of our atmosphere is Gasoline which produces CO2 and is emitted into the atmosphere when Gasoline is used. There are 7 major alternate resources for Gasoline that will not only be beneficial to the Earth’s environment but may be less expensive than Gasoline. One of the 7 major alternate source for Gasoline is the fuel Ethanol. Ethanol is a renewable fuel made from corn (not necessarily always corn) and other plant materials or biomass (organic matter used as a fuel)

lead can enter the body by inhalation or absorption. Lead can be inhaled when lead dust‚ mist‚ or fumes are in the air. The most common source of this contamination comes from firing ammunition with lead primers. When the ammunition is fired‚ the lead primer oxidizes with the lead bullet base causing a release of lead fumes into the air. These fumes are inhaled by the officer. The amount of lead fumes inhaled is directly related to the type of firing range the officer is training on. There would
