Download Solution PDFExplanation:
Triple point:
- The temperature and pressure at which a substance can exist in equilibrium in the liquid, solid, and gaseous states.
- The triple point of pure water is at 0.01 °C (273.16K, 32.01°F) and 4.58 mm (611.2Pa) of mercury and is used to calibrate thermometers and compare critical points.
Important Points
- The matter solidifies on the left side of the triple point, not at the triple point.
- The matter liquifies on the upper side of the triple point, not at the triple point.
- The matter sublimates on the right side of the triple point, not at the triple point.
Additional Information
Critical point:
- The limiting equilibrium state of a two-phase system, in which the properties of both coexisting phases become identical.
- In water, the critical point occurs at 647.096 K (373.946 C, 705.103 F) and 22.064 megapascals (3,200.1 psi, 217.75 atm).
