Answer:
No, it is not possible to both superheat and supercool a substance while maintaining its liquid state.
Explanation:
1. Superheating: Superheating refers to the process of heating a substance above its boiling point without it actually undergoing a phase change. This can occur when the substance is heated rapidly or when impurities or nucleation sites are absent. However, superheating is only possible for gases and not for liquids. In the liquid state, the substance is already at or below its boiling point, and further heating would cause it to transition into a gaseous state.
2. Supercooling: Supercooling, on the other hand, refers to the process of cooling a substance below its freezing point without it solidifying. This can occur when the substance is cooled slowly or when nucleation sites for crystal formation are absent. Supercooling is possible for liquids, and the substance can remain in the liquid state even below its freezing point. However, once the temperature drops further or a disturbance is introduced, the liquid will solidify into a crystalline solid.
In summary, superheating is not possible for liquids, and supercooling can occur but only until a certain point where the liquid will inevitably solidify.
