Pure benzophenone melts at 48.1 C. Your sample of benzophenone began to freeze at 47 C. When you repeated this measurement, the sample again began to freeze at 47 C. Give at least two reasonable explanations for this observation.You tried to read the thermometer when your solution containing the unknown began to freeze but were not certain if the reading was 43.5 C or 44 C so you decided to repeat this by melting the solidifying mass. The new reading you observed was clearly 41 C. What happened? Clearly explain your reasoning.
