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"?
