Step 1: To find the approximate freezing point of chlorine, we start with the freezing point of neon, which is -249°C. Then, we add the temperature difference between neon and chlorine, which is 148°C higher for chlorine. Step 2:A more specific definition of freezing point is the temperature at which solid and liquid phases coexist in equilibrium. The normal freezing point is the temperature at which a substance melts (or freezes) at one atmosphere (760 torr = 760 mm Hg = 14.7 psi = 101.3 kPa) of pressure.
