Final answer:
The triple point is the temperature and pressure at which a substance can exist in equilibrium in all three phases: solid, liquid, and gas. To find the triple point pressure at a given temperature and pressure, we can use the triple point values for water as a reference. In this case, the triple point pressure would be approximately 0.0534 atm. The correct option is A.
Step-by-step explanation:
The triple point is the temperature and pressure at which a substance can exist in equilibrium in all three phases: solid, liquid, and gas. It is a unique point on a phase diagram where all three curves intersect.
According to Table 13.4, the triple point pressure for water is 0.01 atm (273.16 K). However, in this case, we are given the temperature (348 K) and pressure (0.0630 atm) at a constant volume.
Since the triple point is the same for all substances, we can use the triple point values for water as a reference to find the triple point pressure. Therefore, the answer is A. 0.0534 atm, which is the closest value to the triple point pressure of water. The correct option is A.
