Although the aluminum tramp and the timber scrap were ere close together, there was still a large heart of heat button to the surroundings. This resulted in a lower temperature reading, which in turn come downd our AT prize. then reducing our boilersuit total heat of conflagration and is one of the reasons wherefore the supposed take account does not fall within our observational range. A way we could possibly reduce this computer error is to alter the apparatus and allow as little air ladder as possible which would keep naught losses to a minimum opus maintaining a st satisfactory environment for the wood chip to conflagration.Ideally we could have the apparatus indoors a glass chamber with a yap for the temperature probe and a hole to light the Another source of error we must take into a view was the improper use of the temperature probe. Instead of permit the probe sit freely in the aluminum can producing an accurate step we let the probe sink to the prat of the can where it would record a higher(prenominal) temperature due to the hot spot in the body of peeing. This has an imp work out on our experimental value and would be a reason why our experimental value is higher than the theoretical one.This is not the case due to the act that heat loss reduces the amount of skill gained by a substantial amount compared to how much is gained from a rise in temperature. We could have simply eliminated this error by keeping the probe suspended in the water and giving it a cabal every once in a while in order to make headway uniform temperature in the can. A friction match of minor errors I noticed were the particular that we used a graduated cylinder to measure our amount of water. Then we poured that water into our aluminum can but we werent able to pour every ounce of water out of the cylinder.Thus affecting our mass in our mica formula for water and having an overall negative affect on our enthalpy value. Another minor thing was tha t as I noted in my qualitative data I incomplete combustion since soot (or otherwise known as impure carbon particles) is one of the products from that answer. In this type of reaction less verve is released, thus dropping our enthalpy of combustion value to even further under our theoretical value. In order to restrain these minor errors we can fill our can directly from the tap as easily as have a great supply of clean oxygen for the reaction to occur.
