-Refer to the diagram of a simple parcel above. What additional information would you need in order to be able to calculate the relative humidity of this parcel?
A) current vapor pressure inside the parcel 
B) temperature outside of the parcel 
C) air pressure inside the parcel 
D) current temperature/capacity to hold water vapor inside the parcel

Quizplus · Accepted Answer

To calculate relative humidity, we need to know the current temperature and the capacity of the parcel to hold water vapor. Therefore, the information about the current temperature/capacity to hold water vapor inside the parcel is needed to calculate the relative humidity. The other options (A, B, and C) are not directly relevant to calculating relative humidity.
