When determining melting point, you need to be aware of several factors that can affect the accuracy of the measurement. Answer the questions below. Keep this information in mind when conducting the melting point experiment. How does the size of a sample affect the melting point measurement? The larger the sample, the more accurate the measurement. The sample should not be large, because a large sample would produce a higher and broader mp range. The size of the sample doesn't affect mp measurement. How does the rate of heating affect the melting point measurement? A slow rate of heating produces a more accurate measurement. Slow heating can cause a thermometer lag, which would result in a reading lower than the actual mp value. The rate of heating does not matter.

Answer:

(1) The sample should not be large, because a large sample would produce a higher and broader mp range.

(2) The rate of heating does not matter.

Explanation:

(1) The sample should not be large, because a large sample would produce a higher and broader mp range, because varying temperature range across the body will lead to inaccurate determination of melting point.

(2) In principle, the melting temperature is INDEPENDENT (not dependent) on the heating rate. so in other words, altering the heating rate does not affect the measure of melting point.
