Homework Help: Chemistry

student perform 2 melting point determinations on a crystalline product. In one determination, the tube contained a sample 1 - 2 mm in height, and the melting point was 141 - 142 ¢ªC. In the second determination, the sample hight was 4 - 5 mm and the melting range was 141 - 145 ¢ªC. Explain what may have caused the broader range in the second determination. (The actual melting point is reported to be 143 ¢ªC.)

This is my reasoning but I don't know if it is correct. The broader melting range is observed in the second one because the sample of the height was greater.
