Air conditioners not only cool air, but dry it as well. Suppose that a room in a home measure 7.0m X 10.0m X 2.3m. If the outdoor temperature is 30 C and the vapor pressure of water in the air is 90% of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? The vapor pressure from water at 30 C is 31.8 torr.
Explain would the calculated molarity of NaOH be too high or too low If the KHP weighed in your experiment today was contaminated with some unknown inert substance.
To eliminate heating the bodies of water surrounding the power plant, the evaporation of the coolant water is what cools the steam; the water vapor generated by this evaporation is released to the atmosphere
