Document Summary

Chem 111 general chemistry by ebbing gammon chapter 5. 1 5. 3. Gasses can be compressed into smaller and smaller volumes. Most of the math around gases is based on the single ideal gas law vp=nrt. What is gas and how we measure it: Pressure the force exerted per unit are of surface. Pascal the si unit of pressure, with units. Barometer a device for measuring pressure of the atmosphere. 1 torr (or 720mm of mercury) is equivalent to the pressure of air at sea level. Manometer a device that measures the pressure of gas or liquid in a vessel. Definition: the volume of a sample of gas at a given temperature varies inversely with the applied pressure. Pressure produced by the gas is not constant. Boyle law only applies to gasses at low to moderate pressures. Higher pressures will deviate the results from the ideal gas law.
