A sample of air at 21C has a relative humidity of 58%. At what temperature will water
Question:
Problem 11.97
The percent relative humidity of a sample of air is found as follows: (partial pressure of water vapor/vapor pressure of water) ×100. A sample of air at 21°C was cooled to 15°C, where moisture began to condense as dew. What was the relative humidity of the air at 21°C?
Step by Step Answer:
The vapor pressure of water at 21C is 187 mmHg Table 56 Ther...View the full answer

In this video, the concept of pressure has been explained. The bottle is filled up with water, remove the pipe, and now you can see the clear flow of water from the holes due to liquid pressure.You can see that the second layer is holding the weight of the first layer and the third layer holding the weight of both upper layers, that’s why liquid flows out wider from the third as compared to the first two.At the first hole, water doesn’t roll along the walls; it flows out at an angle.At the second hole, you’ll see that the water flows out at a wider angle as compared to the first hole.At the third hole, we can see that the flow of water is much wider/greater than the other holes.This proves that the pressure at the bottom of the bottle is much more than the pressure at the top layers.
