a student carefully measures the melting point of a solid material. she measures the range to be 81.2 - 83.7 degree. assuming she has done the measurement correctly. what can she conclude about the sample, and why
It is not a pure sample because the melting point range is too large.
Can DrBob222 please explain why it is not a pure sample?
Thank you in advance.
Based on the given information, the student can conclude the following about the sample:
1. The melting point of the solid material lies within the range of 81.2 - 83.7 degrees.
2. The measurement accuracy is important to note, as the range is quite narrow (2.5 degrees).
3. The sample material has a specific temperature at which it changes from a solid to a liquid.
4. By carefully measuring the melting point, the student can determine the purity of the sample.
It is important to note that the student must consider any experimental uncertainties and variations that might affect the accuracy of the measurement. However, assuming that the measurement was done correctly, the range provides an indication of the melting point of the sample material.
Based on the measured range of 81.2 - 83.7 degrees for the melting point of a solid material, the student can conclude that the sample has a melting point within this range.
The range provides a measure of uncertainty or error in the measurement process. In this case, the uncertainty is determined by the difference between the maximum and minimum measured values, which is 83.7 - 81.2 = 2.5 degrees.
Since the measured range is relatively narrow, it suggests that the measurement was done accurately. If the student were to repeat the measurement multiple times and obtained a similar range each time, it would further confirm the accuracy and reliability of the measurement.
However, it is important to note that without more contextual information about the specific material or any additional measurements, it is difficult to make any further conclusions about the sample.
