Question

If a solid does not melt when placed in a capillary in a Digi-Melt, which of the following assumptions may be true?

a) High melting point
b) Low melting point
c) Insufficient heating
d) Presence of impurities

Answer 1

If a solid does not melt when placed in a capillary in a Digi-Melt, it could indicate a high melting point or the presence of impurities.

Step-by-step explanation:

If a solid does not melt when placed in a capillary in a Digi-Melt, it could indicate one of the following assumptions:

1. High melting point: The solid could have a high melting point, which means it requires more heat to reach its melting temperature.
2. Presence of impurities: The solid could contain impurities that prevent it from melting at the temperature provided by the Digi-Melt.
3. Insufficient heating: The Digi-Melt may not be providing enough heat to reach the melting temperature of the solid.

Based on these assumptions, the correct answer would be either option a) High melting point or option d) Presence of impurities.
