3. Suppose the relative humidity of the air was 96% on a cold morning
when the temperature was 20 °C. In the afternoon, the air
temperature has risen to 35 °C, but the actual amount of water
vapour in the air is the same as it was in the morning. The
barometric pressure is also the same as it was in the morning.
What is the approximate relative humidity in the afternoon?
17. Which of the following three statements concerning relative humid-
ity valucs of 30% and 40% arc true? Note that when the relative humidity
is 30%, the air temperature may be different than it is when the relative
humidity is 40%.
A. It is possible that at a relative humidity of 30% there is a smaller
partial pressure of water vapor in the air than there is at a relative
humidity of 40%.
B. It is possible that there is the same partial pressure of water va-
por in the air at 30% and at 40% relative humidity.
C. It is possible that at a relative humidity of 30% there is a greater
partial pressure of water vapor in the air than there is at a relative
humidity of 40%.
(a) A, B, and C (b) Only A and B (c) Only A and C (d) Only B and C
(e) Only A
a. If the absolute humidity of air is 27.6 g/kg,
how many grams of water vapor are there in
the 4.8 kg of air?
b. Air at temperature 20.0°C contains some
water vapor. If the partial pressure of water
vapor is 1.98 kPa, what is the relative humidity of
the air in %? The saturation water vapor
pressure at 20.0°C is 2.34 kPa.
c. If the relative humidity of air is 80 % at 18.0°C,
what is the partial pressure of water vapor in the
air in the unit of kPa? The saturation water
vapor pressure at 18.0°C is 2.07 kPa.
