Document Summary

Use 8. (cid:1007)1(cid:1008) j / k (cid:373)ol. Distribution: distribution of fast and slow molecules, maxwell-boltzmann distribution. F(u) = 4(cid:4666) 2(cid:4667: ump = velocity possessed by the greatest number of particle. Uavg = sqrt(8rt/pim: keep up energy in my system and particles will move faster and faster, widen curve to shift average energy in process. The gas molecules are going to spread and uniformly distribute itself in any container it is in. Have big bottle of perfume and you spill, eventually the gas particles will be evenly distributed within the room: effusion. Gas will be traveling through a small opening] If bottle has a small hole and you open the cap, the particles will leave through the small hole: rate of diffusion for gas 1/rate of diffusion for fas 2 = sqrt(m2/m1, g(cid:396)aha(cid:373)"s law. Rate of diffusion of a gas is inversely related to the square root of its molar mass.
