When and why does atmospheric condensation occur?

When Relative humidity and Atmospheric pressure and a certain temperature combine to make a dew point


How long before you get condensation equals liquid?

When the humidity [amount of water vapor in the air] and the temperature are in the right combination, condensation occurs immediately. Condensation can occur at many different temperatures when the humidity is optimal.


Why is not coming water from split ac?

you get condensation (water draining out of a split system) when the relative humidity is high enough. but in order for condensation to occur, your coil must operate at or below the dew point in the immediate area.


Describe the likely temperature and relative humidity that occur during the night?

-35 degrees Celsius.., the relative humidity will be in the high 90%


Do tin roofs condensate?

Condensation can occur in any roof including insulated roof. If there is a difference in temperature between the tin roof and surrounding air (relative humidity) then condensation can occur. Relative humidity is the amount of moisture found in any measure relative to the temperature of the air. The warmer the air the more moisture it 'can' hold. With roofs if you have vented ridge or eaves it will allow air to escape and not form as condensation on the inside. Externally, moisture can form on the outside when the air reaches its dew point i.e. the air gives up the moisture it is holding when it comes into contact with cool surface.


What is ideal humidity in household?

Ideal Humidity. I do not think that there is an ideal humidity. Where I live most people have approximately 40 percent humidity. This must be seasonally adjusted to as low as 20 percent in the winter time otherwise condensation on cold surfaces, such as windows, will occur. Indoor humidity should be reduced or increased relative to the temperature outdoors and personal comfort level indoors


Relationship between evaporation and relative humidity?

The higher the relative humidity is the lower rate of evaporation.


When humidity is being measured what is actually being measured?

Humidity is the concentration of water molecules existing as vapor. The actual measurement is "relative humidity" because it does not determine the volume directly, only the ratio of the volume compared to the maximum the air can hold at that temperature. This dtermines the amount of condensation that can occur if the air is cooled.


Is it possible to have humidity greater than 100 percent?

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.


If it is 23 degrees does humidity add on 2 more degrees?

Is it true that the highest relative humidity on a particular day usually occurs in the mid-afternoon?

No, it is not necessarily true that the highest relative humidity occurs in the mid-afternoon. Relative humidity can vary depending on various factors such as temperature, wind speed, and time of day. In some cases, the highest relative humidity may occur early in the morning or late at night.


When relative humidity is high what is likely to occur?

Well did you factor in how many dicks it takes to make you gag?
