Answer:

#"Saturated"# with what, water vapour?

Explanation:

The #"saturated vapour pressure"# is the vapour pressure of water at a given temperature. When a gas is collected over water, one must always account for #P_"SVP"# at the specified temperature;

i.e. #P_"observed"# #=# #P_"gas"+P_"SVP"#

#P_"SVP"# is a function of temperature; at laboratory temperatures #P_"SVP"~=20*mm*Hg#.

How would you predict #P_"SVP"# to evolve with increasing temperature?
