IB Math Exploration

Although the aluminum brush off and the wood chip were ere close together, there was still a man-sized amount of heat loss to the surroundings. This resulted in a lower temperature reading, which in turn reduced our AT value. Thus reducing our overall atomic number 1 of conflagration and is one of the cerebrates why the theoretical value does not gleam within our experimental range. A way we could possibly reduce this erroneous belief is to alter the apparatus and let as little air making water as possible which would keep energy losses to a stripped while maintaining a stable environment for the wood chip to combustion.Ideally we could down the apparatus inside a glass chamber with a mountain for the temperature probe and a hole to light the Another source of erroneousness we must take into a count was the improper use of the temperature probe. alternatively of letting the probe sit freely in the aluminum evict producing an accurate measurement we let the probe sink to t he bottom of the throne where it would record a higher temperature due to the hot spot in the water. This has an impact on our experimental value and would be a reason why our experimental value is higher than the theoretical one.This is not the aspect due to the act that heat loss reduces the amount of energy 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 hang in the water and giving it a stir every one time in a while in tell to reach unvaried temperature in the can. A couple of minor errors I noticed were the situation that we used a graduated cylinder to measure our amount of water. so 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 isinglass formula for water and having an overall negative affect on our total heat value. Another minor thing was that as I noted in my qual itative data I incomplete combustion since soot (or differently known as impure carbon particles) is one of the products from that reaction. In this case of reaction less energy is released, thus dropping our enthalpy of combustion value to even further below our theoretical value. In order to fix these minor errors we can fill our can directly from the whack as well as have a greater add of clean oxygen for the reaction to occur.
