Air conditioners dry the air while they cool the air. Suppose an air conditioner is used to cool a room that is 7.16 mx 10.60 m x 2.17 m when the outside temperature is 37 °C. At this temperature, the vapor pressure of water is 47.1 torr. The partial pressure of water in the air is 85.5% of the vapor pressure of water. How much water, in grams, is removed from the air each time the air from the room is cycled through the air conditioner? mass of H₂O: g A certain substance has a heat of vaporization of 33.26 kJ/mol. At what Kelvin temperature will the vapor pressure be 4.00 times higher than it was at 307 K? K
