How fast are you personally making the entropy of the Universe increase right now? Compute an order-of-magnitude estimate, stating what quantities you take as data and the values you measure or estimate for them.
Answer to relevant QuestionsA rigid tank of small mass contains 40.0 g of argon, initially at 200°C and 100 kPa. The tank is placed into a reservoir at 0°C and allowed to cool to thermal equilibrium. (a) Calculate the volume of the tank. (b) ...If you toss two dice, what is the total number of ways in which you can obtain (a) a 12 and (b) a 7?Two identically constructed objects, surrounded by thermal insulation, are used as energy reservoirs for a Carnot engine. The finite reservoirs both have mass m and specific heat c. They start out at temperatures Th and Tc, ...A 1.00-mol sample of an ideal gas expands isothermally, doubling in volume. (a) Show that the work it does in ex- panding is W = RT ln 2. (b) Because the internal energy Eint of an ideal gas depends solely on its ...In practical heat engines, which are we better able to control: the temperature of the hot reservoir or the temperature of the cold reservoir? Explain.
