reversible vs irreversible expansions

Postby Elizabeth Bowen 1J » Tue Feb 11, 2020 4:26 pm

If we need to calculate the work of expansion of a system, and we're not told whether it's a reversible or irreversible expansion, how do we know which equation should be used?
thanks

Then it's based on your conditions regarding the system. Is there constant pressure? How about constant temperature? etc.

ok, thanks that makes sense; if we're told that there's not constant pressure, but constant temperature, that means it's reversible, correct?
