Measure the efficiency of a real heat engine and compare it to the efficiency of an ideal heat engine. If you have N squares For the stage A, the air chamber can was placed in the cold bath. What, do you think, determines, the rate of air chamber is moved from the cold into the hot water? 0000047767 00000 n in a box. These cookies will be stored in your browser only with your consent. The manufacturer recommends that this mass does not exceed 200 grams; we will use a 100-gram slotted mass. You need to report the total After you have practiced running the cycle several times - the canister transfers, reading the probe values for temperature and pressure, the height at the base of the piston (mm), and carefullyadding/removing the 100-gram massfrom the top of the piston - you are ready to record the values for a complete cycle. 0000066999 00000 n 0000010330 00000 n Use the exact values for the "five" positions since your final step returning to the cold-water bath without the 100-gram mass might not be identical to the preparation conditions. This is a real 4-step heat engine that has expansion and compression processes in which the engine will do useful mechanical work by lifting a 100-gram mass (and the piston) from one height to another. where N is the number of gas particles, k is the Boltzmann constant which is equal to 1.381 J/K and T is the temperature.

A diagram of the four steps is shown below: When your experimental data has been plotted on a P-V diagram, it will hopefully ressemble the diagram below where there is a close agreement betweenthe state variablesfor Point A (P, V, T) and the values for the cycle's initial preparation conditions. _3j}f4M4sI)*M%Q)-$DR^U?\Xl5- 0000000647 00000 n interested in how many coins end up "head up" or blue. From this diagram, the heat added to the gas and the work done by the engine are measured to determine the efficiency of the engine.

Placing the air chamber in the hot bath will make the temperature of air inside the can to increase.
