When water boils in a pot with a loose lid, the increased pressure forces the lid upward, releasing steam and reducing the pressure in the pot so that the lid drops back down. If the water continues to boil, the lid can rattle upward and downward. Consider a 1 I. pot half filled with boiling water. In this case there is half a liter, or 112 mol, of air and steam above the water. Estimates: mass of the lid is 0.250 kg, lid rises 0.00500 m. Part A Calculate the work done by the steam as the lid moves upward. Express your answer with the appropriate units. w - Value Submit Part B 72-71- Request Answer Submit Treat the process as adiabatic and use the first law of thermodynamics to calculate the drop in the temperature of lid upward.
