Analysis of Problems in the Phase Diagram of the 2015 Revised Curriculum Chemistry II Textbook

[摘要] In this study, six types of 2015 revised curriculum ChemistryII textbooks were analyzed for conditions, definitions, whether or not critical points were displayed, and real-life examples of phase diagram. In this study, it was confirmedthat the problems pointed out in several previous studies were not reflected in the 2015 revised curriculum ChemistryII textbook. The same as the situation defining the phase diagram, the translation of the phase diagram into a phase equilibrium diagram, the distinction between phase and state being unclear, the critical point not being shown in the phase diagram, real lifeexamples are very limited what is being presented as is suggested as a problem. Therefore, it is necessary to reflect the resultsof various previous studies in the revised curriculum ChemistryII textbook that will be made in the future, specify the conditions under which the phase diagram is drawn, newly model the situation defining the phase diagram, and translate the phasediagram as a ‘phase diagram’. It is necessary to use the term, clarify the distinction between phase and state, mark the criticalpoint in the phase diagram, and develop various real-life examples.
