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. WebJan 28, 2014 · If they hit the surface of the balloon straight on (at a 90 ° angle), they exert their maximum force. If they hit the surface at an angle less than 90 °, they exert a smaller force. The sum of all these forces causes the pressure, p, that is exerted by the gas. The diagram above represents a balloon containing molecules of a gas (the red dots).

WebGas exerts pressure because it has mass and has constant random motion above absolute zero.
