All bullets must be addressed in your lab write-up, and a random subset will be graded. design an experiment to demonstrate the ability to convert thermal energy at least partly to net work in a cyclic process, i. e., one that returns the working fluid to its original state (from which the process could of course be repeated). your experiment should produce an obvious net work, such as an increase in the mechanical energy of some object. you have an air-filled cylinder connected by tubing to a small canister that can be moved between a hot-water reservoir—it is hot, so be careful! —and a cold-water reservoir, and a 200g weight. the height of the cylinder and the pressure in the working fluid (air) are monitored by the computer, which will produce a plot of pressure versus height (the file is "heat engine"). you shouldn’t push or pull on the platform. all changes in gas properties should result from placing the 200g weight on, or removing it from, the cylinder’s platform, and movement of the canister between reservoirs. notes: the cylinder’s area is 8.3×10-4 m 2 , and the computer file assumes that the string goes over the middle pulley (not the small or large) in a direction to make the pulley rotate clockwise when the platform rises. the piston should initially be roughly in the middle of the cylinder. if you have any difficulties with the apparatus, ask your lab instructor for .
