Document Summary

Topics covered: 9. 1 gas pressure, 9. 2 relating pressure, volume, amount, and. How much something is pushing on something else. Pascal (n/m2) or (pa) : si unit. Bar : 1 bar = 100000 pa. For atmospheric pressure: a barometer can be used. Easily described as a tube with one end sealed, this end preferably has zero pressure. Mercury is used to assist measuring https://slideplayer. com/slide/5921091/ It can also be measured using a : One end is exposed to a gase. The other end is exposed to the atmosphere https://socratic. org/questions/what-tool-is-used-to-measure-gas-pressure. Pressure can also be measured using a: 9. 2 relating pressure, volume, amount, and temperature: the ideal gas law: Gases have three characteristic properties which include: They take the shape of their container. They occupy a great deal of space. Due to gases inability to be observed directly, there are four distinct properties used to describe them: Volume, pressure, temperature, # of particles (referred to as moles)
