Document Summary

1. (5 pts) explain admonton"s law (the relationship between pressure and temperature at a constant volume and constant amount of gas) using kinetic molecular theory. Kmt: the last postulate given in class states: keavg % t (avg ke is directly prop. to kelvin temp) Pressure of a gas is caused by collisions of the gas particles with the walls of the container. This is determined by: frequency of collisions/unit area : molecular concentration and average speed determine the frequency of collision, force/collision : average molecular speed determines average force/collision. Admonton"s law: pressure and temp are directly proportional (p % t) at constant v and amount of gas. T inc ==> keavg inc ==> u (rms speed) inc (comes from kmt) Average molecular force/coll and freq. of coll. inc. Inc t ==> freq. of coll. /unit area & force/coll inc ==> p inc. Use the van der waals equation in your explanation.
