For this HW problem I'm a little confused as to why q=0. The problem doesn't give you any information about heat so is that why we are just assuming q=0?

The change in internal energy for this problem is solely due to work from compression. There is no mention of using heat or increasing the temperature of the pump. Since the problem only speaks of compression work, it is assumed no heat was transferred.
