lObjective This experiment explores how salt and sugar affect the melting rate of ice in water. Research Questions: * Does adding salt to ice and water slow down‚ speed up‚ or not change the rate the ice melts in the water? * Is salt the only substance to have this effect? What about sugar? Knowing how to speed up the melting rate of ice is very important information for anyone who needs to de-ice roads or driveways after a winter storm. While it seems simple‚ adding salt to ice water

cleaner used (Palmolive‚ Betadine‚ Dettol). These were changed throughout the experiment to compare different effects of cleaners towards bacterial growth. A dependent variable is the factor in which is being measured and observed. In this case‚ the zone of inhibition was measured which was used to determine the area and percentage of the bacteria growth. Constant variables are the factors in which are kept constant to increase accuracy and ensure fairness of the experiment. If the specific variables

Have you ever thought about the reasons why some private schools experience enrollment growth and why others decline? If you were developing a theory of school growth‚ what would you propose as the most important factors that influence enrollment growth? Based on my experiences in working with private‚ Christian and independent schools throughout the country‚ I believe that there are multiple factors that contribute to enrollment growth and decline at a school. Let me highlight some of these factors

In a pure economics sense‚ Brown‚ Gilroy and Kohen(1982) states that “the effect of the minimum wage in the simplest is that employment is reduced and the efficiency of the labour market is impaired because some individuals whose marginal product exceeds their reservation wage are unable to work” (Brown‚ Gilroy and Kohen‚ 1982). The “employment effect” (De Fraja‚ 1999) suggests that an increase in minimum wage will restrict job opportunities‚ resulting in a loss of jobs and potential lowering of

2013 Some Factors that Affect the Rate of a Reaction BACKGROUND: Chemical reactions occur at different rates. In this experiment I will consider some of the key factors that influence the rate of a reaction: * nature of reactants - particle size * temperature * catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction. However

The role of the economy in 1863 – 1968 was the most significant factor‚ but not the only factor‚ in both advancing and reducing civil rights. The economy drove other factors such as was‚ politics and individuals. The underlying tactic of the dominant White American polity throughout the period 1863-1968 was to deny the possibility of African Americans the chance to achieve any degree of prosperity. During the civil war‚ the Republican Party’s philosophy towards African Americans was linked to the

often need organizations that can represent them at work‚ trade unions do exactly that. The purpose of a union is to protect while improving the working conditions of workers. Trade unions exist simply because one person has limited power to challenge or change the decisions that are made about his or her job. By unionizing with other workers‚ chances of having a voice of influence are greater. However‚ there are much arguments about the effect that unions exert on economic productivity and efficiency

“Countries grow at different rates because they accumulate capital at different rates.” Is this true? Explain your answer. Eyeballing any cross sectional data on growth across countries shows that countries grow at different rates. Many theories try to explain this phenomenon with emphasis with capital accumulation being one of them. I will start by developing the standard neoclassical growth model as developed by Solow(1956)[1]. I will then proceed to discuss the extensions that have been made
