1.
The temperature and pressure at which the solid , liquid and gas are in equilibrium.
1. C. The temperature and pressure where liquid, solid ad gas are equally stable and are in equilibrium.
2.D. The solubility of a solid is highly dependent on temperature.
The solubility of solid depends upon the temperature.
