When the agency was melted completely, we had to place the test tube into a address stand and watch the temperature drop. We recorded the temperature of the P-dichlorobenzene every spot. We wrote down the time and temperature. analytic thinking: Looking at the data I collected, it showed that the melting manoeuvre for P-dichlorobenzene was around 52 degrees. The freezing catam enia would be closely 71 degrees. As each instantute passed, the temperature either stayed the same, or decreased. The P-dichlorobenzene seemed to stay at 52 degrees for about 6 instantutes.
