1. Air in a thundercloud expands as it rises. If its initial temperature is 294 K and no energy is lost by thermal conduction on expansion, what is its temperature when the initial volume has tripled?
2.Fifteen identical particles have various speeds: one has a speed of 2.00 m/s, two have speeds of 3.00 m/s, three have speeds of 5.00 m/s, four have speeds of 6.00 m/s, three have speeds of 9.00 m/s, and two have speeds of 11.0 m/s.Find the most probable speed of these particles (in m/s).

Part A What must the initial speed of a lead bullet be at a temperature of 23.0 ∘C so that the heat developed when it is brought to rest will be just sufficient to melt it? Assume that all the initial mechanical energy of the bullet is converted to heat and that no heat flows from the bullet to its surroundings. (Typical rifles have muzzle speeds that exceed the speed of sound in air, which is 346 m/s at 23.0...

Review Constants Periodic Table Air consists mostly of nitrogen (N), with a molecular mass of 28, and oxygen (O2), with a molecular mass of 32. A water molecule (H,O) has molecular mass 18. According to the ideal gas law (N/ V P /KT), dry air at a particular pressure and temperature has the same particle density (number of particles per unit volume) as humidait at the same pressure and temperature. Consequently, humidair, whose low-mass water molecules replace more massive nitrogen...

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...
