The idea of conservation is when someone changes the shape of the substance in which it does not change the amount volume or mass. This is to see if children can think logically. In the experiment there is going to be two girls that are going to be tested over one 9 year and 13 year old. My prediction is that the 9 year old will not be able to conserve. The first experiment was using the 9 year girl. The experimenter first pour the same amount for each cup then ask the participant if there is the

Advantages of fossil fuels * major advantage of fossil fuels is their capacity to generate huge amounts of electricity in just a single location. * Fossil fuels are very easy to find. * When coal is used in power plants‚ they are very cost effective. Coal is also in abundant supply. * Transporting oil and gas to the power stations can be made through the use of pipes making it an easy task. * Power plants that utilize gas are very efficient. * Power stations that

Southwest Airlines Fuel Hedging and Relations to Profitability Abstract In order to stay airborne‚ a passenger airline has to consistently generate profits. Profits come only from paying passengers‚ hence all stratagems must be customer oriented. In a scenario where there are many airlines competing with each other‚ one way of attracting passengers is to keep the cost of flying low‚ while providing value for money.

Fossil fuels comprise 80 percent of current global primary energy demand‚ and the energy system is the source of approximately two thirds of global carbon dioxide emissions as of 2015 (Foster and Elzinga). For decades‚ people have argued about whether fossil fuels are helpful to the planet and sustainability. Although‚ there is no right or wrong answer because renewable and non-renewable resources have disadvantages and advantages. There are very many different variables to be considered in this

INTRODUCTION According to Wikipedia‚ fuel is any material that stores energy that can later be extracted to perform mechanical work in a controlled manner. A fuel contains energy‚ mostly heat‚ which can be released and then manipulated. Most fuels used by humans undergo combustion‚ a redox reaction in which a combustible substance releases energy after it ignites and reacts with the oxygen in the air. Other processes used to convert fuel into energy include various other exothermic chemical

Using ethanol as an alternate fuel‚ or fuel extender includes a heterogenous agglomeration of advantages and disadvantages. On cars: ethanol is preferable to lead as an octane booster. A 10% addition of ethanol to petrol is more effective than lead at boosting octane rating (+2.5) and making car run smoother. It’s cheaper than lead‚ and ethanol-blended fuels leave no gummy deposits‚ thus keeps engine clean. Although a minimal 10% ethanol blend should be compatible with internal combustion engines
