Suppose it is snowing outside and the air is saturated. The air temperature and dew point are both 15$\degree$F, and the actual vapor pressure is 3 mb. If this air is brought indoors and warmed to 75$\degree$F, what would the relative humidity of this air be, assuming that its moisture content does not change? (The saturation vapor pressure at 75$\degree$F is 30 mb).
A) 5 percent
B) 10 percent
C) 30 percent
D) 50 percent
E) 100 percent

Question

Suppose it is snowing outside and the air is saturated. The air temperature and dew point are both 15$\degree$F, and the actual vapor pressure is 3 mb. If this air is brought indoors and warmed to 75$\degree$F, what would the relative humidity of this air be, assuming that its moisture content does not change? (The saturation vapor pressure at 75$\degree$F is 30 mb).​
A) ​5 percent
B) ​10 percent
C) ​30 percent
D) ​50 percent
E) ​100 percent

Quizplus · Accepted Answer

The relative humidity is calculated as the actual vapor pressure divided by the saturation vapor pressure at the new temperature, multiplied by 100. So, (3 mb / 30 mb) * 100 = 10 percent.
