The short answer is the maximum percentage of humidity in the air at any temperature is 100%.

The percentage of humidity or relative humidity of air is the percent of the maximum humidity or amount of water that the air can hold at any given temperature. Therefore if the relative humidity is 80 per cent at 20 degrees and then the air cools off to 18 degrees the relative humidity goes up even though the amount of humidity or water in the air stays the same. If the temperature continues to drop the relative humidity will continue to rise. Since cool air can hold less air than warm air the relative humidity will eventually reach 100%. If the temperature continues to fall the relative humidity will remain at 100% and water will come out of the air as precipitation.

A maximum a 32 degrees Fahrenheit, 0 degrees Celsius. At water's freezing point. Needs humidity plus cold temp


Simply humidity is percentage of moisture in atmosphere or in a gas.When temp. increases pressure reduces, that means gas percentage reduces in unit volume. But due to latent heat of water vapor expansion of vapor is less which results in increase in humidity. And when temp reduces, gaseous volume increases result in less humidity. The above case is for constant water vapor in air. If rain is there humidity increases because of chance of getting to water vapor is more.



tropical climate has high temp. And high humidity where as subtrpoical has high temp. And low humidity




air humidity which condences as air temp' drop


soil humidity, air humidity, soil structure, pH, nutrients availability, temp,



minimum, optimum and maximum temp


lots of things including temp sunlight humidity and atmospheric pressure


They can vary independently - BUT, if the temp goes up AND the amount of moisture in the air stays constant, THEN the relative humidity goes down.


With a temp/rh probe barring that take a humidistat and turn dial when it clicks from closing circuit note the setting and that is humidity surrounding humidistat


varies. affected by temp, humidity, variety, age of the tree and many more


They can change air temp. and humidity in the air.


maximum water temp. for all engines is approx. 90 c


Temp: 78-84 degrees ambient daytime, w/ an 85-90 degree hot spot. Humidity: 30-50%


Humidity needs to be HIGH, Ocean temp needs to be over 82 DEGREES F, and Air Pressure needs to be LOW. END OF DISCUSSION!!!!!!!!!!!!!


the ideal temp for concrete placement is 15-25* C if the temp is above 40*C concrete requires cooling and if it is below 5*C it requires heating. FINDINGS 1> 25mm slump decrease for each *C increase in temp 2> If the temp is 38* C and the humidity is 25% than concrete strength after 28 days can be reduced to 62% as compared to strength if the temp during concreting were 23* C with 90% Humidity !


Well if you want to kill it set it to anything over 100 degrees


When the air temp drops to the dew point that is 100% relative humidity - the air is saturated and condensation willf form. In general, the air temp cannot drop below the dew point so humidities greater than 100% do not occur.


Average maximum temp 57F(14.3C)Average Minimum Temp 42F(7.7C)Rainfall 1.8in(5cm)


Maximum Temp. is -4 degree C. Minimum Temp. is -112 degree C.
