Document Summary

4. 1 an overview of physical states of matter. Gas exerts pressure on the walls of its container. Pressure = force exerted per unit of surface area; = force / area. Earth"s gravity exerts a force uniformly on all surfaces. The mercury in the barometer is in the surface of the dish, and the pressure of the atmosphere pushes the fluid up to a certain height ie. 760 mmhg. The dif in the heights is the pressure dif btwn the flask and the atm pressure. 1 torr = 1 mmhg = 133. 322 pa. 4. 3 the gas laws and their experimental foundations. Ideal gas law (though no ideal gas actually exists) (keep in mind c + 273. 15 = k) V is inversely proportional to p, t and n fixed. V is proportional to t, p and n fixed. V is proportional to n, p and t fixed. Standard temperature and pressure (stp) is 273. 15k and 1 bar.
