When do we use delta H instead of q as in delta S = delta H/T? (when the problem doesn't tell you that it's constant pressure)

Do you always use delta H instead of q during phase changes?

The question states to find the entropy change meaning you would use the delta H of the specific phase change to find the entropy.
