1. (relative humidity) The partial pressure of water vapor in air is usually less than the equilibrium vapor pressure (or saturation pressure) at the ambient temperature; this is why a cup of water will spontaneously evaporate. The ratio of the partial pressure of water vapor to the equilibrium vapor pressure (at the same temperature) is called the relative humidity. Saturated air, at 100% relative humidity, would be in equilibrium with a cup of liquid water. The saturation pressure depends strongly...

The relative humidity of air equals the ratio of the partial pressure of water in the air to the equilibrium vapor pressure of water at the same temperature times 100%. If the relative humidity of the air is 58% and its temperature is 68 oF , how many moles of water are present in a room measuring 12 ft x 10 ft x 8 ft? The vapor pressure of water at 68 oF is 17.54 torr.

Name Dalton's Law of Partial Pressures - Many gas samples are a mixture of gases. For example, air is a mixture of gases. The gases dissolved in blood make up a mixture as well. In a gas mixture, each gas exerts its partial pressure (the specific pressure contribution of the gas to the total pressure of the gas mixture). Dalton's law states that the total pressure of a gas mixture (Pita) is the sum of the partial pressures of the...
