Question: At 25 °C gallium is a solid with a density of 5.19 g/cm3. Its melting point, 29.8 °C, is low enough that you can melt

At 25 °C gallium is a solid with a density of 5.19 g/cm3. Its melting point, 29.8 °C, is low enough that you can melt it by holding it in your hand. The density of liquid gallium just above the melting point is 6.1 g/cm3. Based on this information, what unusual feature would you expect to find in the phase diagram of gallium?
