Air temperature at 20°c can hold 14 grams of water vapor. if an air mass is 20°c and has seven grams of water vapor, what would its relative humidity be?

relative humidity fro 14 gm water vapor is 100%

relative humidity fro 7 gm water vapor is 50%

Explanation:

Given data:

Air temperature of 20 degree celcius can sustain 14 gram water vapor

from table -  saturation mixing ration

saturation mixing ration for air temperature at 20 degree celcius is 14g/kg

therefore relative humidity is %

Air temperature of 20 degree celcius can sustain 7 gram water vapor

from table -  saturation mixing ration

saturation mixing ration for air temperature at 20 degree celcius is 14g/kg

therefore relative humidity is %

what is the question because that is not a question.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
