System doing work on its surroundings
http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch5/work.html WebSep 11, 2015 · My guess is: work done by a system, is the thermodynamical force generated by the system multiplied by its conjugate variable on the surroundings. As in my example here: a gravitational forcefield is generated by the system on the surroundings, and the conjugate variable displacement on the surroundings is multiplied by it.

WebMar 14, 2024 · If work is done ON a system that means the surroundings are working upon the system so work is positive. Work would be positive because the surroundings are adding energy to the system. An example of this is compression. Work being done by the system is negative because the system itself is doing work and therefore losing energy.
