Answer:

The water gas will express a #"saturated vapour pressure"#.

Explanation:

IF you collect a gas over water, you always have to take into account #P_"SVP"#, the #"saturated"# or #"equilibrium vapour pressure"# for a given temperature. #P_"SVP"# values are extensively tabulated. Would you expect #P_"SVP"# to rise or fall with temperature? At a temperature of #100# #""^@C#, can you quote #P_"SVP"#?
