Please help asap !! A sample of water vapor occupies a volume of 10.5 L at 200°C and 100 kPa. What volume will the water vapor occupy when it is cooled to 27°C if the pressure remains constant?

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
