Sources of Error
Some possible sources of error may have been a faulty thermometer and unsealed samples. A faulty thermometer is a systematic error that may cause temperature measurements that are too high or too low. This could completely change the line graph and the overall analysis because the data would be inaccurate. In order to avoid this we could check the accuracy of the thermometer by measuring the changing temperature of a substance with two different thermometers. Another possible source of error could be an unsealed sample which could lead to evaporation. This would be a random error because it would cause different measurements each time due to a decreasing water level. I believe this could be avoided by vacuum sealing the sample in order to ensure that no moisture escapes.
