Is this a spontaneous or nonspontaneous process?
![10.86 The enthalpy of vaporization for water is 40.65 kJ mol-!.
As a design engineer for a project in a desert climate, you
are exploring the option of using evaporative cooling.
(a) If the air has an average volumetric heat capacity of
0.00130 J cm3K, what is the minimum mass of water
that would need to evaporate in order to cool a 5 m X
5 m room with a 3 m ceiling by 5°F using this method?
