Relative humidity is defined as the partial pressure of water vapor in the air, expressed as a percentage of the saturation vapor pressure at that temperature. Consider a room 10 m x 10 m x 3 m in which the air has been completely dried. A bucket containing 10 L of water is brought into the room. What is the equilibrium partial pressure of water vapor in the air at 25 degrees Celsius, and how much water remains in the bucket after equilibrium is finished?
Due to a failure in the building's cooling system, the room's temperature rises to 37 degrees Celsius. Does all of the rest of the water evaporate? What is the partial pressure of water vapor in the room? What is the relative humidity?
