A piston-cylinder device contains 0.05 kg of steam at 1 MPa and 300 °C. The steam now expands to a final state of 200 kPa and 150 °C. During the process, 2 kJ of heat is lost to the surroundings. Assuming the surroundings to be at = 25 °C and = 100 kPa, determine: (a) The work done by the steam. Answer: [W] kJ (round to one decimal place) (b) The exergy of the steam at State 1. Answer: [X1] kJ (round to one decimal place) (c) The reversible work that can be done by the steam. Answer: [Wrev] kJ (round to one decimal place) (d) The exergy destroyed during this process. Answer: [Xdes] kJ (round to one decimal place) (e) The second law efficiency of this work producing process. Answer: [etaii] (round to two decimal places)

Potassium (K) is a metal in the first column of the periodic table, directly underneath sodium. Its behavior is similar to sodium. Potassium metal is poisonous. However, the compound potassium chloride (KCl) is edible and tastes salty. What best explains this? HINT: Same logic as sodium example in lecture.
