A psychrometer consists mainly of two thermometers mounted side by side: a dry bulb thermometer and a wet-bulb thermometer. The dry-bulb thermometer determines the temperature of the air. The second bulb-covered with a s... More »

Higher temperatures make higher levels of humidity possible. This is because warm air is capable of holding more moisture than cold air. Warm air has a stronger bond to water molecules, making the air feel drier and allo... More »

People are most comfortable whenever the relative humidity level is around 45 percent says HowStuffWorks. A level of 100 percent humidity means that the air is saturated with water vapor and unable to hold more. When thi... More »
