Experiment used to determine the amount of released energy from combustion (if things change in the future)

  1. Place a frame, build a furnace partially inside the frame, complete the frame. The furnace is now perfectly insulated and will no longer loose temperature (unless ore is added) nor explode from high pressure
  2. Add fuel (perfect 2:1 is not required) via a pipe, use over 1000 mol of O2, remove the pipe attached to the furnace
  3. Record all mol amounts and temp with a tablet (atmos cartridge), convert temp to K (add +273)
  4. Ignite furnace, record all mol amounts and temp with tablet, convert temp to K
  5. Calculate moles of combusted O2 (= moles before - moles after)
  6. Calculate the Thermal energy in the gas, before and after (Thermal energy = Temp * sum(mol of each gas * specific heat)
  7. Calculate energy released per mol of combusted O2 (= TE.after - TE.before) / moles of combusted O2)
  8. Deconstruct the furnace completely to disarm it safely, or connect a single pipe so it can burst and act as a vent
  9. Alternatively: A circuit could maybe also be used to capture the temperature and pressure at the point of ignition... before the furnace explodes (the pressure will be around 200MPa)

Improved experiment

  1. An advanced furnace with connected LED consoles to accurately track temperature and pressure was prepared, a MIPS program was written to calculate the released energy

Spark energy experiment

  1. A small amount of N2 was placed in an advanced furnace. The TotalMoles and Temperature values were recorded, the specific heat was looked up in game and found to be 20.6
  2. Ignite was pressed 2 times, each time the new Temperature was recorded, the increase was the same
  3. The energy added per ignite was calculated as: EnergyChange = moles * specificHeat * TemperatureChange
  4. The obtained value was 4.99999 J per ignite.
  5. The experiment was repeated with a larger amount of N2. The obtained value was 5.0126 J per ignite.
