How much water vapor does 1 cubic meter of air contain at a temperature of + 10 ° C if its relative humidity is: a) 100% b) 50% c) 10%?
To solve the problem, first it should be noted that at a temperature of +10 degrees Celsius, 1 cubic meter of air can contain approximately 9 grams of water vapor.
In this case, at a maximum humidity of 100%, the water vapor content will be equal to:
100% * 9 = 1 * 9 = 9 grams.
With a relative humidity of 50%, we get:
50% * 9 = 0.5 * 9 = 4.5 grams.
With a relative humidity of 10%, we get:
10% * 9 = 0.1 * 9 = 0.9 grams.
Answer: 9; 4.5; 0.9 grams, respectively.
