A)Molecular masses for O2 and N2 are 32 u and 28 u, respectively. What is the ratio of the root mean square speeds of oxygen to nitrogen at 30 ◦ C?

B)What is the ratio at 97 ◦ C?

2- A heat engine absorbs 305.176 J of heat from a hot reservoir and expels 65.984 J to a cold reservoir. When it is run in reverse, with the same reservoirs, the engine pumps 305.176 J of heat to the hot reservoir, requiring 239.192 J of work to do so. Find the ratio of the work done by the heat engine to the work done by the pump.

    10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
