Final answer:
The question involves thermodynamics and the behavior of steam in a closed system when heated, requiring the use of steam tables or specialized software to accurately determine the final pressure.
Step-by-step explanation:
The question involves the properties of steam and the changes in pressure when heat is added to a closed system. It pertains to the principles of thermodynamics, which is a branch of physics. As the pressure of a contained gas is related to both its temperature and volume (which remains constant in this case), an understanding of the gas laws is required to answer the question. According to the ideal gas law, the pressure and temperature of an ideal gas are directly proportional when the volume is constant. For a real gas or steam closer to its condensation point, however, one might consider using more complex equations of state like the van der Waals equation. However, for the question at hand, detailed steam tables or property data software packages are often used to determine the final pressure of steam at a specific temperature, as ideal gas laws and other equations of state might not give accurate results for steam near the condensation point.
