not many vehicles start well underwater......
It's considered high humidity, and anything above 50%.
Altitude is the height above sea level
As the sun goes down, the temperature drops and the capacity to hold water vapor in the air decreases increasing the relative humidity above 0 percent
It would depend on the air temperature inside the classroom. There are differences in data, but generally, experts with Energy Star and the Consumer Products Safety Commission agree that 40 percent is considered to be an acceptable relative humidity point. The CPSC says this is the minimum (and below that a humidifier should be used) while this is in the middle of what Energy Star recommends (between 30 and 50 percent). Regardless, a room should never be above 60 percent as mold and bacteria grow easier above 60 percent relative humidity.
Yes especially if your mother got porked by your father and his friend analy
If the relative Humidity of a certain material or spot in your house is above 80 percent. You will get fungus and damp.
Here is the table showing the relationship between temperature and humidity levels. To adjust and monitor the humidity level in your room, use a humidifier. Well-known brands such as Dyson, Keecoon [with large capacity above 2 Gallon], Panasonic, etc.
Usually above 150,000miles
Yes, but not under normal circumstances. At, or above, 100%, condensation would take place on anything that could act as a nucleus - such as a dust particle in the air.
This is the measure of relative humidity. At 50 percent relative humidity, the air is holding half of what it could. It is relative humidity because it is related to the temperature and pressure of the air.
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.
percent above 18 - 99% percent above 24 - 84%
