Unformatted text preview: equals pressure times distance times volume in the area of the process. 3. Heat does change from each point, but only slightly from B C and D A. 4. Yes, there is work done in each process but the net work of the whole process is close to zero A C is positive and from C A is negative. 5. The total heat added goes to zero and the net work is zero so the change in internal energy is zero in the complete cycle. Conclusion: In the experiment the thermodynamic work done does turn out to be equal to the mechanical work done. We found the work done with the different formulas and the ratio is close enough to one. This was the work done from the different heights but the net work of the whole process is zero because it returns to the original position. Also, the change in internal energy of the complete cycle is zero, because the heat leaves by the end of the process. So both the internal energy and work done is zero for the complete cycle....
