as the two components are poured into the beaker the starting temperature is measured from the thermometer hanging in the beaker from the ring stand. The temperature was then measured every 5 seconds for the next 95 seconds. In these 95 seconds there was an evident sign of a chemical reaction that had taken place. Over time, the temperature had increased by almost 18°C due to the exothermic reaction that had taken place. In this experiment there were several occasions where there may have been human error. One of these errors may have been that when measuring the temperature it was almost always constantly increasing causing the individual reading the temperature to may read Aditya BindraWeber P.310/29/09
the temperature incorrectly. The hypothesis of this experiment was supported because once the vinegar and sodium bicarbonate chemically combined, an exothermic reaction took place. This was shown when the data illustrated that the temperature of the compound progressively increased.
