An astro-geological survey of a carbonaceous chondrite meteorite identified three solid mineral specimens, designated Alpha, Beta, and Gamma. The physical properties of these specimens were recorded in the laboratory and are detailed in the table below:

Mineral SpecimenMelting Point (∘C^\circ\text{C}∘C)Boiling Point (∘C^\circ\text{C}∘C)Electrical ConductivityDensity (g/cm3\text{g/cm}^3g/cm3)
Alpha98280Non-conductor in all states1.82
Beta35504827Non-conductor in all states3.51
Gamma7721935Non-conductor as a solid; conducts when molten or dissolved in water2.15
a.
