Question

If water vapor comprises 3.5 percent of an air parcel whose total pressure is 1,000mb, the water vapor pressure would be:
A. 1,035mb
B. 35mb
C. 350mb
D. 965mb

Answer 1

Hint: The air pressure adapts to the surroundings of the parcel and is always equal to the air pressure inside the parcel’s air pressure. After the expansion, the parcel pressure decreases gradually because of the air temperature due to the upward movement of the air parcel. During the compression, the air temperature in the parcel increases due to the downward movement of the air parcel.

Complete answer:
The water vapor pressure would be 35 mb because if the water vapor comprises 3.5 percent of the air parcel and the amount of the total pressure would be 1,000 mb. The temperature of the air parcel decreases due to the cause of work and expansion of the raised air parcel. The humidity increases until it reaches 100% inside the air parcel and the largest aerosol particles forming the excess water vapor during the cloud droplets in the beginning. It makes less sense as it rises during the expansion of the air parcel and increases in altitude because the air pressure starts decreasing around the parcel. But sometimes it became less dense when the temperature of the rising parcel was found in the coolest state.

Therefore, the correct option is (B).

Note: In the atmospheric air the thermodynamic properties and basic dynamic in which the imaginary body of the air to be assigned. The number of density more outside the parcel than the number of density inside the parcel when the air temperature of the air surrounding is less warm than the inside parcel of the air temperature.
