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.
SO2 + H20 --> H2SO3
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?
