IN WHICH CASES THE WORK DONE BY THE SYSTEM IS POSITIVE?

Dear tuparla,

There are two conventions. One says that work done on the system is positive, the other says that work done by the system is positive.

Chemists tend to use the former, physicists tend to use the latter... one of several reasons it's not a good idea to take thermodynamics in chemistry and physics at the same time.

Please feel free to ask your queries here. We are all IITians and here to help you in your IIT JEE preparation.

All the best.
