Very pure liquid water can be subcooled at atmospheric pressure to temperature well below 273.15 K (0°C). Assume that 1 kg has been cooled as a liquid to 267.15 K (-6°C), A small ice crystal (of negligible mass) is added to "seed" the subcooled liquid. If the subsequent change occurs adiabatically at atmospheric pressure, what fraction of the system freezes and what is the final temperature?
