Why is it necessary to use a powder rather than a crystalline sample when determining melting point?
Answers
Answer:
with a crystalline solids ,transfer of heat will not be uniform which can cause an error in the determination of the melting point of a substance .
Answer:
Even heating.
Explanation:
When we use a crystalline substance that is clumped together, the heat provided to the substance may be unequal, resulting in uneven melting. If the substance does not melt evenly, it creates calculation errors for analyzing, which is why we break it down into a powdery form and spread it evenly to avoid calculation errors before melting it. This is also why a certain chemical is not heated fast towards its melting point. It ensures uniform heating and heat transmission to the substrate while avoiding overheating or melting. The uniform heat ensures equal spread of kinetic energy of the particles.
