Define what is the minimum mass of water to evaporate

Reference no: EM13656736

Define the enthalpy of vaporization for water is 40.65 kJmol21. 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 cm-3 K-1, define 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 5F using this method? (b) Is this a spontaneous or no spontaneous process?
