Q223
The maximum water vapour held in the atmosphere is
A.
Absolute humidity
B.
Saturation point
AnswerC.
Relative humidity
D.
Absolute transpiration
Answer: Option B
Solution
Answer: Option B
Solution:
The maximum water vapour held in the atmosphere is Saturation point.The water-vapour content of the atmosphere varies from place to place and from time to time because the humidity capacity of air is determined by temperature.
At 30°C (86°F), for example, a volume of air can contain up to 4% water vapour. At -40°C (-40°F), however, it can hold no more than 0.2%.
