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 allowing more water to bond with air.
Humidity lowers air pressure by displacing nitrogen and oxygen molecules with lighter water molecules. Differences in humidity can cause storms to form. Humid air also presents challenges to pilots.
Humidity in a home causes discomfort for occupants. If the levels are too high, the moisture encourages the growth of mold. Keeping humidity in the recommended 30 to 60 percent range requires a multi-step approach that includes venting, using HVAC systems and a dehumidifier.
Humidity can be measured by using a hygrometer. Types of hygrometers include the basic psychrometer, an electrical impedance hygrometer useful for remote locations, the condensation principle hygrometer and mechanical hygrometers.
Using a humidifier, boiling water, adding water sources and hanging clothes to dry are some ways to increase a room's humidity. Humidifiers range in size and capability. Some are made for distributing moisture throughout an entire house, while others are made just for one room. Humidity increases in
People manage home humidity levels in several ways, including properly ventilating clothes dryers and washers outside, running fans to have air continually circulating, operating whole-house dehumidifiers and keeping air conditioning units properly cleaned and functional. Some people select housepla
Humidity can reduce static electricity. Water conducts electricity, so humidity in the air allows static electricity to leave objects.
When the relative humidity in a plant's environment rises, its rate of transpiration lowers, and a decrease in humidity causes the transpiration rate to rise. Air that is humid does not accept water vapor easily, and drier air makes it easier for a plant to release water by evaporation through the s
Humidity in a house can be decreased by installing extractor fans, opening windows to increase air circulation and installing insulation. Having good ventilation and raising indoor temperatures are two of the key objectives when trying to control humidity.
The main effect humidity has on hair is to make it curly or frizzy. The change in texture of the hair is caused by the increase in hydrogen atoms in the air.
