The purpose of a humidifier is to increase the moisture content of the air in the room or home. Humidifiers are often used in the winter in homes and buildings where heating systems are in heavy use. They can be bought as small room units or whole house units.Know More
Humidity is a measure of how much moisture is in the air compared to the maximum amount possible. This measurement is typically given in terms of a percentage, rarely as a ratio or fraction. Low humidity in the air, otherwise known as dry air, can exacerbate many respiratory conditions. It can lead to dry lips and skin, nose bleeds and even the common cold. A humidifier can increase the humidity of the air to improve comfort and respiratory health.
A humidifier must be cleaned regularly to prevent the growth of mold and bacteria in the device, which will be blown around the house. If moisture is found on windows and other surfaces, the appliance should be turned off to prevent contamination.Learn more about Weather & Tides
Hot air rises and cold air sinks due to varying densities. Given the same volume of air, hot air is generally less dense compared to cold air.Full Answer >
Hot air rises and cold air falls because cold air molecules are densely packed together, making them heavier, and hot air molecules have more space between them, making them warm enough to rise. It is for this reason that hot air balloons move upwards. In addition to temperature affecting air density, humidity plays a role.Full Answer >
When a cold air mass meets a warm air mass, a front is formed; if the cold air is replacing the warm air, it is known as a cold front. Cold fronts frequently cause rain showers or thunderstorms because they force air in a steep upward direction at the front's edge. They also bring about changes in wind direction and atmospheric pressure.Full Answer >
A warm air mass that is cut off from the ground is said to be an occluded front. Occluded fronts generally occur in areas of low pressure and create stormy conditions and changes in temperature and wind speed.Full Answer >
