Graph for Heat energy from Compost Project
Posted: Sun Feb 07, 2016 2:44 pm
Hello Moderators ,
Note : Plz read the procedure so that you can have a better understanding of what I am talking about.
Procedure: https://www.sciencebuddies.org/science- ... procedurel
I started doing the project, "Decomposing Energy: Extracting Heat Energy from a Compost Pile," which I found on the Science buddies website. I already bought all of the materials and am halfway done.
I want to do have at least three graphs in this project, but there are barely any hints to make one in this project:(. On step 7 at the end it says: "Note: Just before running the fan, take a compost pile temperature reading and record the reading in your lab notebook, along with the date and the time." So, I was thinking, the first graph could be something like Day, Temperature, Time on first aeration,Temperature before second aeration,Time on second aeration, Temperature before third aeration, time on third aeration. I would prefer something simpler and if you can make some changes that would be great.
At the end I read:
"Equation 1:
Q = mC∆T
Q = Heat energy in joules (J)
m = Mass of the water or the coffee can, in grams (g)
C = Specific heat capacity. For water, the specific heat capacity is 4.186 joules/grams °C for tin 0.227 joules/grams °K
∆T = Change in temperature in degrees Celsius (°C)"
This looks like a very interesting thing that could be made into a graph, but I do not know how to do it. Can you please give me with some pointers on how to make the graph? For the third graph, I feel like I am missing something from the procedure. Step 9D says: "Subtract the weight of the empty coffee can from the weight of the water-filled coffee can to arrive at the weight of the water. Record this value in your lab notebook. The purpose of the water-filled coffee can is to help you determine how much heat energy the compost pile is producing." I need to include this in my notebook anyway and it seems it has some potential for a graph. So, I need to know what to put for the third graph. I really need an answer by today if possible. I have no other options to make the graphs and I think that you guys would have the best answer because of your experience. Thank You for taking the time to read this, if you can do this to help me and probably others who may be doing this in the future, I would be in great debt of you guys and I would greatly appreciate it.
