Question

The total volume of a new house is 681 m3. Before the heat is turned on, the air temperature inside is 15°C, and the relative humidity is 42 percent. After the air is warmed to 20°C, how much water vapor must be added to the air to make the relative humidity 42 percent?  ________kg

Expert Solution
Approach:

The air in atmosphere has water vapour in it; corresponding to the partial pressure of water vapour at a given temperature, the phase of water lies in superheated region.  

The relative humidity of air tells us about how much water vapour can be added more before saturation is achieved.

The mathematical expression of relative humidity is
