We did a lab proving the conservation of thermal energy using a calorimeter. Our objective was that the calorimeter lab report heat lost by hot water was the heat gained by the cold water. My group got 20% error!! What are the possible sources of it? 2 following 4 answers 4 Report Abuse Are you sure you want to delete this answer? Yes No Sorry, something has gone wrong.

This is because you must have opened the calorimeter when you added the cold water. Thus, heat was lost not only to the cold water but to the surrounding environment. Also, you might not have waited long enough for the thermometer to read, so the temperature of the hot water was lower than it really was, or the temperature of the cold water was w

There is no such thing as an exact measurement. If the mass of an object is determined with a digital balance reading to 0.1 g, the actual value lies in a range above and below the reading. This range is the uncertainty of the measurement. Remember every https://ibchemistrysl.wikispaces.com/Errors+and+Uncertainty+in+Experimental+Data time you take a measurement, the last digit recorded represents a guess. If the same object is measured on a balance reading to 0.001 g the uncertainty is reduced, but can never be completely eliminated. Every measurement has an inherent uncertainty. We therefore need to give some indication of the reliability of measurements and the uncertainties in the results calculated from these measurements. When processing your experimental results, a discussion of uncertainties should be included. When writing the conclusion to your lab report you should evaluate your experiment and its results in terms of the various types of errors. To better understand the outcome of experimental data an estimate of the size of the systematic errors compared to the random errors should be considered. Random errors are due to the accuracy of the equipment and systematic errors are due to how well the equipment was used or how well the experiment was controlled. We will focus on the types of experimental uncertainty, the expression of experimental results, and a simple

View Full Document Andrew Rosen Mrs. Davidson Period 6/7 December 14 th , 2009 Heat of Neutralization Lab Questions: 1) What is the largest source of largest source of error in the experiment? The largest source of error in this experiment was probably the amount of solution added to the calorimeter. At times, human error made it so the amount was not exactly 50.0mL like the lab dictates. Also, during this lab, the solution was not mixed frequently and this could have caused inaccurate temperature readings and thus make the results askew. 2) How should the two heats of reaction for the neutralization of NaOH and the two acids compare? Why? The two heats of reaction for the neutralization of NaOH and the two acids should be rather similar because the same amounts of moles of NaOH are added to both acids. This should naturally cause the temperature difference () to be equal. The individual initial and final temperatures, however, can be different. The moles of products are all equal as well. This also should hold true since both HCl and HC 2 H 3 O 2 are strong acids/electrolytes. 3) The experimental procedure has you wash your thermometer and dry it after you measure the temperature of NaOH solution and before you measure the temperature of the HCl This preview has intentionally
