I always have problem figuring out when work is done by or on system/gas.
Here's how I understand it, pleasure correct me if they are wrong:
Work done by system/gas indicates expansion(volume increases,) and work is positive.
Work done on system/gas indicates compression(volume decrease) and work is negative.
Also, I am guessing that work done by "system" and work done by "gas" is the same thing, but is this assumption even correct? I was looking through past forums on this topic only to be confused even more. Please help!
