Reynolds 02 Show that in the high temperature limit, both the Einstein model heat capacity hwE where r = KT Cy = 3Nk- (ez – 1)2 and the Debye model heat capacity hwD r'edr 3 Cy = 3Nk where rp KT (e² – 1)2| agree with the law of Dulong and Petit. (HINT: Expand e/(e – 1)2 in a power series in r and retain only the first nonzero term. Extra Credit: What is the second nonzero term?)

Natural gas (CH.) fuel relcases 50 MJ per kilogram of fuel combusted. The reaction is CH, + 20, CO2 + 2H;0 Calculate the energy released per kilogram of CO2 emitted. [Energy released is Eepe E, where Eris energy released per kilogram of fuel combusted, mf is mass of a kilogram-mole of fuel (CH.), and mr is mass of a kilogram-mole of carbon dioxide (CO2). The Molecular mass of an atom of carbon, hydrogen and oxygen are 12, 1 and 16 respectively.]

Vocals Q Search What is AU of 1.0 kg of water? Express your answer with the appropriate units. View Available Hint(s) AU=340 J Previous Answers - Part B Correct SOLVE The change in the potential energy of 1.0 kg of water in falling 35 m m is AU mgh= (1.0 kg)(9.8 m/s)(35 m) -340 J + ☆. Suppose the dam is 80% efficient at converting the water's potential energy to electrical energy How many kilograms of water must pass through the turbines each second to generate 47 MW of electricity?
