Question
Part B - How Relative Humidity Changes with Temperature in a Typical Day The way relative humidity can change with temperature over the course of a typical day (autumn) is shown in the figure below. In the figure, the air temperature increases during the daytime as the Sun warms Earth, and it cools during the nighttime after the Sun has set. .Assume that the actual amount of water vapor in the air (expressed as specific humidity here) is 10 g/kg, and that it remains constant over the course of the days The water vapor capacity expressed as the saturation-specific hum attached to the image below. t at vanous emperatures needed to calculate rela e humid s o de n etable · You will label the respective relative humidity. Each relative humidity label is associated with the temperature indicated on the curve. Drag the appropriate labels to their respective targets Hints Hint 1. Relative Humidity and Temperature If the specific humidity is held constant throughout the day, changes in air temperature will affect the relative humidity by changing the saturation specific humidity. Ar increase in air temperature will increase the saturation specific humidity and decrease the relative humidity; a decrease in air temperature will decrease the saturation specific humidity and increase the relative humidity. Hint 2. Calculating Relative Humidity The specific humidity and the saturation specific humidity at a given temperature are needed to calculate relative humidity. With those two variables, the relative humidity can be determined by dividing the specific humidity by the saturation specific humidity, and multiplying that result by one hundred.Explanation / Answer
Given,
Relative humidity= specific humidity/ saturation specific humidity
So by dividing 10 with each SSH value will give their relative humidity
So the answer is
Air temperature. SSH. RELATIVE HUMIDITY
1). 10 7.57 1.32
2). 12 8.65 1.15
3). 14. 9.86 1.01
4). 16 11.23 0.89
5). 18. 12.76 0.78
6). 20 14.47 0.69
7). 22 16.39 0.61
8). 24 18.52 0.54
9). 26 20.89 0.48
10). 28. 23.53 0.42
11). 30 26.46 0.38
From above result it shoshows that at constant specific huhumidi when temperature increases, relative humidity decrease
Happy chegging and dont forget to review my answer
Thank you :)
