Document Summary
Insignificant effect on one another unless they collide: gases expand to fill containers, take volume and shape of their containers. Four properties define the physical behaviour of a gas: amount of gas molecules, volume, temperature, pressure. If g and d are constant, we use h to describe pressure: manometers are used to measure gas pressure, similar to a barometer but measures pressure differences using liquid. Boyle"s law: kept the mass of gas and the temperature constant and studied the relationship between pressure and volume, pressure and volume were inversely proportional. If the pressure was doubled then the volume goes to : pv = constant, (cid:883)(cid:883) = (cid:884)(cid:884) If you were to combine charles" law and boyle"s law: v/t = constant, (cid:2869)(cid:2869)(cid:2869) =(cid:2870)(cid:2870)(cid:2870) Avogadro"s law: equal volumes of different gases, at the same temperature and pressure, contain equal numbers of molecules, gas volume is proportional to the number of molecules and subsequently the number of moles, v/n = constant.
