Feb 9, 2020 at 12:19 | comment | added | Bob D | @kimi each step is infinitesimal but the accumulation for the entire process is not. For example after half the sand has been removed the other half has been elevated the entire height of the expansion to that point. And don’t forget the gas expands against constant atmospheric pressure knee the entire process | |

Feb 9, 2020 at 9:58 | comment | added | lee_dong-eun | This is the scenario which led me to ask this question. You say sliding the weight off horizontally requires less work, but the increase in height of the piston is infinitesimal as well, right? | |
