of Table H
-
Define the term vapor pressure.
-
What is the vapor pressure in kPa and atm of
water at 100oC?
-
What is the vapor pressure in kPa and atm of
ethanoic acid at 120oC?
-
What is the vapor pressure in kPa and atm of
propane at 75oC?
-
Compare the vapor pressure of the four
liquids at 70oC.
-
Liquids boil when the vapor pressure is
equal to the pressure on the system. For instance, water boils at 100oC
at 1atm but when the pressure is 2 atm water boils at 118oC.
Consider the four liquids boiling at 70oC, what is the pressure on
the system for each liquid?
