Question

2. Figure 2 shows the relationship between humidity and air temperature. figure and do the following: Refer to the a) Assume four parcels ofair all have a relative humidity of 70%. Parcel A h temperature of 22° C, parcel B has a temperature of 22° F, parcel C has a temperature of 3C, and parcel D has a temperature of -2° C. Which parcel, A, B, C, or D, has the most humid air in terms of total water vapor content? air in terms of total water vapor content? D rose to 75%, would the total water vapor content parcel D be higher, the same or as a Which parcel has the dricst If the relative humidity of parcel ower than the total water vapor content of parcel A, assuning parcel A retains a relative humidity of 70%? b) The dew point temperature (T) is the temperature at which an air parcel becomes saturated (100% relative humidity, dew forms). Air that is undersaturated must cool to this temperature before dew (or frost) will form. Determine whether or not the following conditions are saturated or undersaturated. RH stands for Relative Humidity. T-14"C T."6"C T=14°C RH-97 % RH:100% RH-9796 RELATIONSHIP BETWEEN AIR TEMPERATURE AND SATURATION VAPOR PRESSURE 50 40 30 S 20 To -20-1010 20 30 40 Temperature (c)

Explanation / Answer

parcel a has absolute humity =.014

parcel b has=.02

parcel c has =.04

parcel d has .003

parcel c has most humid air in terms of water vapour content

parcel d has driest air

water vapour content would remain same.

2) a. saturated

b.saturated

c.saturated

d.unsaturated

e.saturated
