Which of the following would we expect this situation?

Question

in the application section of the work file you were given the following situation: You have measured the temperature of the air in a room and have found it to be 75 degrees f with 80% relative humidity. **If the amount of water vapor that was contained in the air at that time does not change, but the temperature is decreased over time. Which of the following would we expect this situation?

Answer 1

I don't see any of the following. But know that if the amount of water stays the same and the temperature goes down the relative humidity will go up and some kind of precipitation may occur.

Answer 2

To answer this question, we need to understand the relationship between temperature and relative humidity. The amount of water vapor the air can hold depends on its temperature. Warmer air can hold more moisture, while cooler air can hold less moisture. When air is at 100% relative humidity, it is saturated and cannot hold any more moisture.

In the given situation, the temperature is 75 degrees Fahrenheit with 80% relative humidity. This means that the air is not saturated and can potentially hold more moisture. Now, if the amount of water vapor in the air does not change, but the temperature decreases over time, we can make the following expectations:

1. The relative humidity will increase: As the air temperature decreases, its ability to hold water vapor reduces. If the amount of water vapor in the air stays the same, but the temperature decreases, the air becomes closer to its saturation point. This leads to an increase in relative humidity.

2. Condensation or fog may occur: If the decrease in temperature is significant and the relative humidity reaches or exceeds 100%, the air becomes saturated, and condensation occurs. This can result in the formation of fog or visible droplets of water on surfaces.

So, in summary, if the amount of water vapor in the air remains constant but the temperature decreases over time, we would expect an increase in relative humidity and the possibility of condensation or fog if the saturation point is reached or exceeded.
