We are likely to have our highest relative humidity blank in the day:
about sunrise
If two temperatures read nearly the same when in a sling psychrometer, you can conclude:
the air has a high relative humidity
The dew point is the temperature at which:
water vapor condenses to a liquid
When air temperature increases, the saturation specific humidity:
increases
A BETTER indicator of the actual amount of water vapor in the air is:
dew-point temperature
If the air temperature remains constant, evaporating water into the air will what the dew point and what the relative humidity
increase, increase
The type of fog that results from the evaporation of falling droplets into the air is known as:
precipitation fog
Frost forms through through the process of:
deposition
When warm, moist airs, moves over a colder surface, fog may result:
advection
All of the following units can be used to represent humidity except:
km
If the temperature remains unchanged and the specific humidity drops, the RH will increase:
false
If the specific humidity remains unchanged and the temperature drops, the RH will increase:
true
The absolute humidity of the air is expressed as a percent:
false
The capacity of air to hold water vapor is temperature dependent:
true
The relative humidity is a measure of the airs actual water vapor content:
false
Dew point is ALWAYS given as a percent:
false
Relative Humidity is always given as a percent
true
If you turn on your oven and open its door, the increase in air temperature should raise the RH inside your home:
false
Suppose the air temperature inside your home is 30C and you lower it to 26C. As long as the moisture content of the air inside does not change, the Relative Humidity should increase:
true
Steam fog forms as a mass of cold, dry air passes over a warm, moist surface:
true
