Question

Arrange the given pictures in ascending order according to the air pressure at the highest point in each case.

(A) (i), (ii), (iii)
(B) (ii), (iii), (i)
(C) (ii), (i), (iii)

Answer 1

In our atmosphere air has some pressure value. But this pressure is not the same in all the places. The pressure may go from one place to another. And the pressure may change for different heights also. Depending upon the height of the places which are given in the question, the solution can be determined.

Complete step-by-step solution: The air pressure is also called atmospheric pressure, it is the force exerted on a surface by the air is called air pressure or atmospheric pressure. It is commonly measured with a barometer. The atmospheric pressure or air pressure is determined by the level of the mercury rises in the barometer.
Mainly the air pressure is caused by the weight of the air molecules. This pressure helps the air molecules at the earth's surface to be more tightly packed together, then the air pressure increases in the atmosphere as the height decreases. And the air pressure is also increasing when the air cools. The density of the air becomes denser and it pushes more air down the ground, so the pressure is increased when the air gets cooled. When the air gets hot, the pressure of the air decreases. So, the increase in pressure depends upon decrease in temperature of the air and then decrease in height.
Thus, the height increases, the air pressure increases.
Hence, the option (A) is the correct answer.

Note:- By comparing the three pictures, the mountaintop is very high compared to the other two pictures. And by comparing the remaining two pictures the high building is high when compared to the sea level. The solution must be in ascending order, so at the top of the mountain the pressure is low compared to the sea level.
