Solution
The factor that does not affect the melting point range of a substance is "which sample slot in the apparatus you put your sample in".
Here's why:
-
How much sample is packed: The amount of sample can affect the melting point because a larger sample may take longer to melt completely, which could broaden the observed melting point range.
-
How quickly the apparatus increases in temperature: The rate of temperature increase can affect the melting point range. If the temperature increases too quickly, the sample may not have enough time to melt completely at its true melting point, which could result in a higher observed melting point.
-
How tightly the sample is packed: The packing of the sample can affect the melting point because a tightly packed sample may take longer to melt completely, which could broaden the observed melting point range.
-
Which sample slot in the apparatus you put your sample in: This does not affect the melting point of a substance. The melting point of a substance is a physical property that is independent of the location of the sample in the apparatus.
