On the midterm does anyone know if we have to convert our answers for delta U into joules? Or can we leave it as L.atm?

I would say convert it to joules just in case if they don't specify

I would assume that we would have to convert it to joules. since U is the internal energy, and energy is measured in joules, they would probably expect us to give the answer i joules. but the conversion from L*atm to joules is given on the formula sheet, so you don't have to memorize it, just remember to do it.

I believe you would need to convert it since U is supposed to be in terms of J or kJ. Like someone said, the formula to covert it is on the formula sheet so I would think that you need to convert it. I’m not sure if the TAs will take off points if you leave it in L•atm, but I would just convert it to be safe
