Spontaneity of Solid Phase Change Two crystalline phases of white phosphorus are known. Both contain P4 molecules, but the molecules are packed together in different ways. The a phase of the solid (P4; densitya 1.82 g/cm) is always obtained when molten phosphorus crystallizes below the melting point (44.1 °C). However, when cooled below -76.9 °C, the a phase spontaneously converts to the ß phase (P4; density=1.89 g/cm3). P4(s, 0) – P4(s, 8) Indicate which of the following statements are true...
