6) average relative speed 平均相对速率 1. The average speed of molecules in a system relative to a molecule is expressed and the average relative speed between two molecules is given on the basis of Maxwell velocity distribution law. 根据麦克斯韦速度分布律,表示出系统内分子相对某一个分子的...
VWhen a bucket of water is sThe average speed of molecules is inversely proportional to the square root of their mass. A small molecule such as nitrogen or oxygen has molecular mass≈30DaDa=30uu,where the dalton(DaDa)and the...
Two containers, one containing hydrogen and the other containingoxygen, have been in contact and able to exchange heat for a very long time, so thatmolecules of both gases are at the same temperature. The average speed of theoxygen moleculesis 400 m s-. Find the average speed ofthe ...
Homework Statement Suppose an oxygen molecule traveling at the speed of 484 m/s bounces back and forth between opposite sides of a cubical vessel 0.1 m on...
True or False: For a given transfer of energy, a greater change in disorder occurs when the temperature is high. True or false? Molecules of greater mass have a lower average speed than those of less mass at the same temperature.

where R is the gas molecule constant, T is the thermodynamic temperature; M is the molecular mass of the gas (in moles). At the steady temperature, υ¯ can be a constant for the same kind of gases. In addition, the geometrical factor of the porous body can be expressed as (9-42...
A second type of average gets around these difficulties; it is the weight average, M¯w, where the weight of each molecule is considered important, not the number. We introduce the term Wi, which is the weight of the fraction with molecular weight Mi. The weight of fraction i can be ...
