Question

Please answer both Questions

1- Draw a generic phase diagram, presuming no supercritical fluid. Label the diagram, including the triple point and phase boundaries. If I have 251 g of a sample of water at standard atmospheric pressure and -11.2°C, and apply 103 kJ of heat, what overall phase transition, if any, will occur? Justify your answer, and label it on your diagram.
