2. Which of the following would cause relative humidity to increase?
a. Adiabatic warming of the air
b. Cooling the air
c. Removing water vapor from the air
d. Decreasing the mixing ratio

answer: b

are these correct?

Yes, your answers are correct.

1. The primary control of how much water vapor the air can hold is the temperature of the air. As the temperature increases, the air can hold more water vapor.

2. Cooling the air would cause relative humidity to increase. When air is cooled, its capacity to hold water vapor decreases, so if the amount of water vapor in the air remains the same, the relative humidity will increase.

Yes, both of your answers are correct!

For question 1, the primary control of how much water vapor the air can hold is the temperature of the air. Warmer air can hold more water vapor than cooler air. This is because as the air temperature increases, the molecules of air move faster and escape more easily from the liquid phase, allowing more water molecules to enter the gas phase.

To determine this answer, one can study the concept of "humidity" and the factors affecting it. By understanding that temperature directly affects the capacity of air to hold water vapor, one can conclude that temperature is the primary control.

For question 2, cooling the air would cause relative humidity to increase. Relative humidity is a measure of how much water vapor is in the air compared to the maximum amount of water vapor the air can hold at a given temperature. When air is cooled, its capacity to hold water vapor decreases, so the same amount of water vapor becomes a higher percentage of the air's maximum capacity, leading to an increase in relative humidity.

To determine this answer, one can consider how changes in temperature impact the capacity of the air to hold water vapor and how relative humidity is calculated. By cooling the air, the ratio of actual water vapor content to the air's maximum capacity increases, resulting in an increase in relative humidity.
