At a given pressure, the vaporization temperature of water and the temperature of saturated steam are given from the steam table

Question

BlackTom AI · Accepted Answer

In this true/false item, we first consider what the steam table provides for a given pressure. 
Option 1: True. The steam table lists saturation properties at a specified pressure, including the saturation temperature (the boiling/saturation temperature) for both the liquid phase (water) and the vapor phase (saturated steam). At the same pressure, the temperature at which water vaporizes (the vaporization or boiling temperature) is exactly the saturation temperature, which is the temperature shown for saturated liquid and for saturated steam. Therefore, the vaporization temperature of water and the temperature of saturated steam coincide at that pressure and are both given in the steam table. 
Option 2: False. This would assert that the steam table does not provide or equate these temperatures, or that they differ at the same pressure. However, by definition of saturation in steam tables, the water is at its boiling point when it is in equilibrium with saturated steam, and the corresponding temperature is the same for both phases at that pressure. Thus, this option contradicts the fundamental meaning of saturation properties. 
Overall, the statement aligns with how steam tables are organized for a given pressure, where the vaporization (boiling) temperature of water equals the saturated-steam temperature, and both are listed as the saturation temperature for that pressure.
