  1. Is the sealed rigid container 100% filled with liquid water? Different answer!
  2. Is the sealed rigid container partially filled with water? Now you must consider whether the void space is air plus water vapor or vacuum plus water vapor.
  3. Ideal gas partial pressures linearly add. You are given a simple question. Give the simple answer - though you would do better to give a more complete answer. The vapor pressure of water at 25 C is 0.031258 atmospheres abs. -- Uncle Al
