They are the same...........

Explanation:

The aqueous vapour pressure, or more commonly, #"the saturated vapour pressure"# is the vapour pressure exerted by water molecules at a particular temperature, and these SVP's are extensively tabulated. When we collect a volume of gas by water displacement, the pressure in the collecting vessel is given by....

#P_"collected"=P_("gas")+P_"SVP"#

And thus we need tabulated values of #P_"SVP"# at various temperatures. Typically #P_"collected"=1*atm#.
