Question

A Carnot engine is operated between two heat reservoirs at
temperatures of 520 K and 300 K. If the engine receives 6.45 kJ of
heat energy from the reservoir at 520 K in each cycle, how many joules
per cycle does it discard to the reservoir at 300 K?

Practical steam engines utilize 450C steam, which is later exhausted at 270C. (a) What is the maximum efficiency that such a heat engine can have? (b) Since 270C steam is still quite hot, a second steam engine is sometimes operated using the exhaust of the first. What is the maximum efficiency of the second engine if its exhaust has a temperature of 150C? (c) What is the overall efficiency of the two engines? (d) Show that this is the same efficiency as a single Carnot engine operating between 450C and 150C. Explicitly show how you follow the steps in the Problem-Solving Strategies for Thermodynamics.

A block made of cobalt with a mass of 0.80 kg is heated to 850°C, then dropped into 5.00 kg of water at 10°C. What is the total change in entropy (in J/K) of the block-water system, assuming no energy is lost by heat from this system to the surroundings? The specific heat of cobalt is 420 J/(kg · K), and the specific heat of water is 4,186 J/(kg · K). (Hint: note that dQ = mcdT.)
