For w=-delta(nRT), is it the change in moles or temperature? I've read the posts here and they've had different answers. Thanks :)

In midterm 2013 question 3A, the temperature is constant and the delta sign applies to the number of moles. I believe that when you are asked to calculate the work done by a certain system and use this equation, it will be at a specific temperature (i.e. boiling/melting point) and the change is in regards to the moles.

The change is in the number of moles, not the temperature.
