How does a gas exert a pressure

WebMar 4, 2024 · We begin by recalling that the pressure of a gas arises from the force exerted when molecules collide with the walls of the container. This force can be found from Newton's law (2.6.2) f = m a = m d v d t in which v is the velocity component of the molecule in the direction perpendicular to the wall and m is its mass. WebThe pressure of a sample of gas is measured at sea level with a closed-end manometer. The liquid in the manometer is mercury. Determine the pressure of the gas in: (a) torr. (b) Pa. (c) bar. Solution. (a) 264 torr; (b) 35,200 Pa; (c) 0.352 bar. The pressure of a sample of gas is measured with an open-end manometer, partially shown to the right.
