Chemistry 261 - Investigative Experiment Report Form Experiment 1: Determination of Capillary Melting Points \& Boiling Points Questions 1. If the Mel-Temp apparatus is heated too quickly errors occur due to a difference in the actual temperature of the sample and the temperature read on the thermometer. a. Which do you think changes temperature more quickly as the Mel-Temp apparatus, the capillary tube with the sample or the thermometer? In other words, which has the larger heat capacity? b. Based on your answer to part a, would the actual melting point be above or below the observed temperature of the thermometer? - As a result, the actual melting point would be .... 2. Chemists use the melting and boiling points to identify substances because these are constants and are relatively easy to measure. Explain why the bp and MP are relatively easy to measure? Reality check: 3. We learned that liquids would boil at temperatures far below with reduced pressure. Given this information, explain why many recipes recommend increased cooking time at high altitudes? 4. While driving at high altitudes, sometimes cars may fail to run due to the formation of vapor locks. Explain your rationale?
