P5. Supercooled water II In an isolated container, which has cooling tubes built in the walls, an amount of m = 18 kg clean water is very carefully cooled down to the temperature of ti = -9 °C. After this a small ice crystal of negligible mass is thrown into the water, which starts the freezing of the supercooled water. Determine the amount of ice produced!
