Bcus when it's at 25 deg celcius, steam is no longer gaseous so I can eliminate it out of my eqn. So you can just imagine the qn as what happens if you connect your vessel of nitrogen to an empty vessel and allowed to cool to 25 deg celcius. Then you'll see that PV = nRT Only V and T changed, so what's the new P?
