U=q or U=q+w?
When is the change in internal energy (U) equal to heat (q) and when is it equal to heat+work (q+w)? What is the difference between U=q and U=q+w?

so U is always U=q+w, so as I understand it, U=q when there is no work being done by or on the system.

Re: U=q or U=q+w?
Yes this is true, the change in U= q + w. The change in internal energy is equal to the heat in the case that there are no other processes taking place except that of transferring energy as heat.
