  Coal Calculations

  

      Coal to KiloWatt Calculations

  This activity appears to focus on coal and energy, but it will serve to make one aware of the diverse information explored with in APES.  

  This summer activity is an introduction to the kinds of problem solving is explored in APES.  On the first day we meet, we will explore how different students approach "getting at" the solutions. Since we have not had opportunity to discuss related information you will need to explore the internet to pull in additional information.  One has a summer to explore possible solutions.

  Grade is based on identifying applicable data from internet and developing a logical approach to solving  solutions.  NOTE:  I am interested in problem solving more so than getting the "correct" answer.

  First think through how the background information below relates to the questions asked below.  You will need to download Google Earth to access some information.

  Background:

  1. Of several coal cars observed, typically the capacity was 144,000.  Pounds is assumed for the quantity.
  2. Sulfur content is in question for coal usage and resulting pollution problems.  Use the Google Earth KMZ file to determine possible source of coal.  Google Earth will open up to the location this picture was taken.  Useful data concerning coal can be located at USGS.  Be sure to look for applicable data on this site.
  3. Missing parameters (conditions) may be defined by student, but must be defendable and explained on paper.
  4. Show work using conversion factors (factor label method) to obtain answer.  This topic was introduced in chemistry courses.  If you need an review consider looking for dimensional analysis.
  5. For background you may need to get a better understanding of kilowatt - hours and how it might apply to question(s) below.  Use the formulas provided below for the overview.
  6. Consider reading information located at NET.org.  Where does this equation fit in?  

  SO₂ + H₂0 --> H₂SO₃

  Questions:  

  1.  Approximately how many Mj of energy would be produced from one coal car?

  2.  Approximately how many kilowatts could be obtained from the loads of coal found in these four coal cars?  

  3.  How long would your home energy needs be provided for by these four coal cars?  Show all work and explain bases for determining solution.

  4.  How many pounds of sulfuric acid might form per coal car?
