9.1: Gas Pressure - Chemistry LibreTexts
2022年10月27日 · The pressure of a gas may be expressed in the SI unit of pascal or kilopascal, as well as in many other units including torr, atmosphere, and bar. Atmospheric pressure is measured using a barometer; other gas pressures can …
5.1: Gas Pressure, Temperature, Volume, and Chemical Amount
2023年5月2日 · Gas pressure is caused by the force exerted by gas molecules colliding with the surfaces of objects (Figure 5.1.1 5.1. 1). Although the force of each collision is very small, any surface of appreciable area experiences a large number of collisions in a short time, which can result in a large force.
9.1 Gas Pressure - Chemistry 2e - OpenStax
Gas pressure is caused by the force exerted by gas molecules colliding with the surfaces of objects (Figure 9.2). Although the force of each collision is very small, any surface of appreciable area experiences a large number of collisions in a short time, which can result in a high pressure.

2024年7月11日 · Figure \(\PageIndex{2}\): The effect of temperature on gas pressure: When the hot plate is off, the pressure of the gas in the sphere is relatively low. As the gas is heated, the pressure of the gas in the sphere increases. This relationship between temperature and pressure is observed for any sample of gas confined to a constant volume.
Gas Pressure: Definition, Formula and Solved problems
2019年4月9日 · Gas Pressure – Gases exert pressure on any surface with which they come in contact because gas molecules are constantly in motion. – We, humans, have adapted so well physiologically to the pressure of the air around us that we are usually unaware of it, perhaps as fish are not conscious of the water’s pressure on them.
