The equations used are valid only if the working substance of an engine is assumed to be an ideal gas. W.H. P0exp (27016, 39936) so our results are not accurate. In the experiment, where a heat engine apparatus would be used, hot and cold baths would be considered as the heat reservoirs and mechanical work would be inferred from the up and down motions of the piston. 0000022409 00000 n 0000034908 00000 n 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.
