WebIf the system does work, its internal energy decreases, if work is done on the system, its internal energy increases. As we are usually interested in how the internal energy of the system changes, that is the usual sign convention. Let's look at the example of volume work. Expansion means that the volume increases, but expansion is the system ... WebMay 3, 2024 · 187. 15. Precursor : Sign conventions regarding Work by the system/on the system may even vary among Physics textbooks and among Chemistry textbooks and as a rule of thumb it is better to clearly mark out the convention used by the text being referred to specifically and remain consistent with it. Generally the rules/ resulting implications ...
