text: You solve these sort questions by calculating the energy contained in the sample (blocat?) and the water initially, and realizing the final energy content must be the same, or less if the system has lost energy to the environment.\n\nIf you actually run this experiement in a lab, you will find that the final temperature is the same as the air temperature of the lab.  If it would be warmer, you did not wait long enough, the system would lose energy to its environment.  The 2nd Law of Thermo prevents the reverse from occurring.  This is probably not the expected answer, but I believe it is correct.
