Review of the Apparent Paradox in the Measurement of Atmospheric Pressure vis-a-vis estimation of Pressure of Air within an enclosure

The air surrounding the planet earth has its weight, which presses anything on the surface of the earth, or any imaginary surface assumed to be constructed at any point and in any direction of its thickness. This weight factor has been suit­ably defined to be the physical parameter universally known as the pressure of air atmosphere. The measurement of this parameter has proceeded in two different ways viz, Hydrostatic approach and kinetic theory approach. But the two proce­dures apparently may lead to a certain apparent anomaly under specific cases. In this discussion one such anomaly is discussed and attempt has been made to show that the anomaly is not real and that the two concepts are really the two ways of looking at the same thing.
