The health care costs of obesity in the U.S. were estimated to be as high as $190 billion in 2005, (2) a number that is double earlier estimates, and that is expected to rise, along with obesity rates, over the coming decades. This includes money spent directly on medical care and prescription drugs related to obesity.
Ferric chloride is a red-orange solid that has hygroscopic properties. Chemical Formula: FeCl 3. Layman's explanation: Ferric chloride is a corrosive chemical, thus, it is used to deodorize sewage and industrial waste by partially reducing to ferrous chloride.It is also employed as an engraving reagent on metal surfaces. Other applications include its use as a flocculating agent in water treatment.hemical Formula: FeCl 3.

A hygrometer is weather instrument used to measure the amount of humidity in the atmosphere. There are two main types of hygrometers â a dry and wet bulb psychrometer and a mechanical hygrometer. What is Humidity? Humidity is the amount of water vapor in the atmosphere caused by condensation and evaporation. It can be measured as absolute humidity (the amount of water vapor in a unit volume of air), or as relative humidity (the ratio of moisture in the atmosphere to the maximum moisture the atmosphere can hold). 1  It is what gives you that horrible sticky feeling on a hot day and can cause heat stroke.
