Known constant humidities can be created by materials whose affinity for water regulates the water vapor pressure in the atmosphere surrounding the material. Among the more readily controllable materials are salt solutions and acid solutions. Numerous lists of the humidities created by various salts and acid concentrations appear in literature, inferring a certain ease of producing the specified humidity conditions. An ease of maintenance of these humidity conditions with high accuracy is also inferred since the temperature dependency is very small. The ease of handling and low low cost of salts has promoted the widespread use of salt solutions as humidity generators.

Is it salf to drink hydrogen peroxide?
It's not a good idea. From the web site of the CDC (Center for Disease Control): Ingestion of dilute solutions of hydrogen peroxide may result in vomiting, mild gastrointestinal irritation, gastric distension, and on rare occasions, gastrointestinal erosions or embolism (blockage of blood vessels by air bubbles). Ingestion of solutions of 10-20% strength produces similar symptoms, but exposed tissues may also be burned. Ingestion of even more concentrated solutions, in addition to the above, may also induce rapid loss of consciousness followed by respiratory paralysis.

How do you control chlorination of methane?
the chlorination of methane does not necessarily stop after one chlorination. it may actually hard to get a mono substituted chloromethane. instead di, tri, and even tetra-chloromethanes are formed. one way to avoid this problem is to use a much higher concentration of methane in comparison to chloride. this reduces the chance of a chlorine radical running into a chloromethane and starting the mechanism over again to form a di-chloromethane. through this method of controlling product ratios one is able to have a relative amount of control over the chloromethane.
Corrosion Science and Control?
corrosion science and control means the act of scientist prevent corrosion and find the way to control it
Define relative humidity?
Water can "dissolve" in air. As the temperature and pressure of air goes up, the amount of water that can be held in the air increases. We can measure the "absolute" humidity of air, but this isn't especially useful. It is more handy to know hoe much water is IN the air, as a percentage of the amount of water the air COULD hold. That's "relative humidity". It is important because as the temperature rises, the air COULD hold more water, so the relative humidity falls. As the temperature falls, the relative humidity rises. As the air cools, when the air couldn't possibly hold any more water than it has now, the relative humidity is 100%, and we call this the "dew point", when dew will begin to settle onto the grass. If the air gets much colder, the water will condense out of the air and form FOG.

What is the purpose of a humidistat?
A humidistat is a device used to control the operation of space conditioning systems such as air conditioners, dehumidifiers and humidifiers. When used with an air conditioner, for example, the humidistat cycles the unit on and off based on humidity rather than temperature as provided with a regular thermostat. A humidistat set at 70 percent relative humidity, for instance, will cycle the air conditioner on when relative humidity reaches 70 percent or above, even if the thermostat setting does not call for cooling.

Does congestion control ensures that the network does not become saturated at any one point?
Congestion control does ensure that the network does not become saturated at any one point. This ensures that there is no compromise in the quality of service.
