Because we grew up in a pressurized system, our bodies have developed so that all pressures interior toour body are relatively close to atmospheric pressure. With small pressure differentials, we have a difficulttime gauging the magnitude of atmospheric pressureConsider a person lying on his stomach, with sheets of paper stacked on his back. If each sheet of paperhas a mass of 3.500 g and is the standard letter size (8.5" x11"), how many sheets would stack to producea pressure on his back equal to atmospheric pressure (roughly 101325 Pa)?
