Document Summary
Volume of a gas is altered significantly by changing the applied for or the temperature. Gases flow more freely and have much lower densities than liquids and solids. Gases mix in any proportions to form solutions, unlike liquids and solids. Difference in the physical states are due to greater average distance between particles. Manometer: device used to measure pressure of a gas in an experiment. Closed-end: difference in column heights = gas pressure. Open-end: atmospheric pressure +/- difference in column heights = gas pressure. Ideal gas: a gas that exhibits linear relationships among volume, pressure, temperature, and amount. Boyle"s law: relates pressure and volume at a constant temperature and n. Volume is inversely proportional to pressure or and. Charles" law: relates volume and temperature at a constant pressure and n. Volume of any amount of gas at 0k is 0. Avogadro"s law: relates volume and n at a constant pressure and temperature.
