What should the dew point and humidity be to use a evaporative cooler?
At 32°C (90°F) and 15% relative humidity, air may be cooled to nearly 16°C (60°F).At 32°C (90°F) and 50% relative humidity, air may be cooled to about 24°C (75°F).At 40°C (105°F) and 15% relative humidity, air may be cooled to nearly 21°C (70°F).
Why is there high relative humidity in basements in the summer?
1) Warm air can hold/contain more water vapor than cool air. 2) Relative humidity is a measure of how much water is in the air as compared to the maximum it can hold. Thus if you take some warm summer air and send it into a nice cool basement, the air will cool and as cool air can hold less water than the warm air, the relative humidity of the cooled air in the basement will go up.
Humidity of air?
Humidity is when the air is very moist. So when it is humid out, there is water vapor in the air.
What happens when air pressure is cooled?
When the air is cooled it mostly rains
What describes the air level of air saturation?
relative humidity Humidity is the term that describes the level of air saturation.
If air is compressed and cooled sufficiently it becomes a substance?
If air is compressed and cooled, the temperature of the air will become negative. Now depending on how much humidity there is in that air being compressed we might get some water droplets as it is being cooled. Carbon dioxide when compressed and cooled we get dry ice.

What happens when air that has reached its dew point is cooled further?
Relative humidity increases
Will an air conditioner remove humidity too?
Yes, A/C units inherently remove moisture as the air is cooled. anonymous@oola.com
How does a change in temperature affect relative humidity and specific humidity?
When the temperature of air is cooled or reduced the relative humidity (RH) increases. The moisture content of the air remains the same until the RH rises to the point of 100% saturation and condensation occurs.
What happens to the humidity of air as it is warmed or cooled?
The amount of water win the air will not change but the amount of water the air will hold rises as temp rises. Enter condensation.
Does an air conditioner add humidity to a room?
The simple answer is no. What an air conditioner does, is cool air (obviously). When air is cooled however, it loses its ability to hold moisture. Therefore, the relative humidity (Water vapor/Capacity) of the air in the room will increase despite the fact that no moisture was added.
Why outer surface of a cooled bottle gets wet at room temperature?
Humidity in the air condenses on the cool bottle surface.
Is condensation formed because energy is added?
Condensation happens when air is cooled below a temperature called its 'dew point' which is the temperature at which the humidity is 100%. Air is capable of absorbing more water vapour when it is hotter. Therefore if warm air with water vapour in it is cooled, the humidity rises, until at the dew point the humidity is 100%. If it is cooled further, some of the water vapour appears as liquid water, which we call condensation. A typical example of condensation is fog, which happens when warm, moist air arrives over cooler ground, and it gives up its water vapour as floating droplets.
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.

Describe what happens when air is cooled to its dew point?
The dew point is the varying temperature at which atmospheric humidity condenses. If the air temperature drops below the dew point, dew and condensation form.
