Document Summary

Chapter 5- gases and the kinetic- molecular theory. Corresponding changes for liquids and solids are much smaller. The volume of a gas can be altered significantly by changing the applied force or the. Gasses flow more freely and have much lower densities. Gases mix in any proportions to form solution. Differences in the physical stats are due to the greater average distance between particles in a gas. Summary of section 5. 2 that the atmosphere can support (760 mmhg at sea level and 0c) Gases exert pressure (force/area) on all surfaces they contact. A barometer measures atmospheric pressure based on the height of a mercury column. Closed- end and open end manometers are used to measure the pressure of a gas. Pressure units include the atmosphere (atm), torr (identical to mmhg) and pascal (pa, the si unit) sample. Summary of section 5. 3 pressures pressure (p), temperature (t) and amount (number of moles, n)
