The temperature-dependent phase diagrams, from 40 to -50 °C, of the binary (NH4)2SO4/H2O system are derived from data collected in a low-temperature, single-levitated-particle apparatus. The conditions of vapor pressure, temperature, and composition, at which particle phase transitions occur along the path of increasing relative humidity, define the equilibrium phase diagram, whereas the set of...
