Either add the work done on the system or subtract the work done by the system. The work must result in random change in molecular momentum and change the heat content of the system. | |

| Aug 18, 2023 at 5:09 | comment | added | Poutnik | Is not it obvious ? If W is work done to system then W= +ΔA. If by the system then W=-ΔA. It is not about intuition but about historical context. Work done by the system was used by engineers/physicists, more interested what the system can do. Chemists/scientists were interested more in what happens to the system. | |
