4. When performing a melting point on a solid compound using a melting point apparatus, two melting point determinations were made. One sample, which was 1 mm in height in the capillary, possessed a melting point of 200.0-200.5°C. The other sample was 25 mm in height. What would you expect the approximate melting point to be for this sample, assuming identical heating rates of 1°/min? (Hint: heat is applied from the bottom of the sample) (Give an actual numerical approximation!)

Question
4. When performing a melting point on a solid compound using a melting point apparatus, two
melting point determinations were made. One sample, which was 1 mm in height in the
capillary, possessed a melting point of 200.0-200.5°C. The other sample was 25 mm in
height. What would you expect the approximate melting point to be for this sample,
assuming identical heating rates of 1°/min? (Hint: heat is applied from the bottom of the
sample) (Give an actual numerical approximation!)
5. For the same solid compound as the question above, if the 1 mm sample was heated at 60°
per minute on a melting point apparatus, what would you expect for an approximate
melting point? (note that at this heating rate, the sample will melt rather quickly, but again
give an actual numerical approximation)
