Question

You are carefully watching the temperature of your melting point apparatus as it is heating up. At 132 C it is still a white solid. Your friend asks you a question, after answering you look back at the melting point apparatus and the temperature is 138 C and the solid is fully melted. What do you do?

Answer 1

Answer:

See the answer below

Explanation:

Since the experiment is set out to determine the melting point of the white solid, after missing the melting point due to distraction, there are two possible solutions and both involves a repeat of the experiment.

1. The first one is to allow the molten substance to solidify again and then repeat the experiment. This time around, a critical attention should be paid to be able to notice the melting point temperature once the temperature gets to 132 C.

2. The second solution would be discard the molten substance and repeat the experiment with the a new solid one. Similarly, critical attention should be paid once the temperature gets to 132 C since it is sure that the melting point lies within 132 and 138 C.
