Quizplus · Accepted Answer

The axes on a phase diagram represent temperature and pressure. These two variables are used to determine the state of a substance, whether it is in solid, liquid, or gas phase, or the conditions under which it undergoes phase transitions. The temperature axis is usually plotted on the horizontal axis and the pressure axis on the vertical axis.
