The pressure and volume of the engine's gas is measured during the entire cycle, and the work done by the engine is computed. It is important to take your measurements of temperature, pressure, and piston height as quickly as possible after each transition stabilizes since the apparatus does leak air slightly and you want the completed cycle to return to its initial conditionsproviding youwith a closed PV diagram to analyze. 0000038012 00000 n 0000048697 00000 n 0000101274 00000 n 0000028198 00000 n This is achieved when the mass on the platform is not changed. the time-reversed sequence will lead to a decrease in entropy. 0000046241 00000 n Determine the total work done by enclosed gas in various thermodynamic cyclic processes.
