Question

Can someone help me please? thanks!

Answer 1

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`.
