### How to know which method to use?

On quizzes and exams, is there going to be an instance where they are going to ask us to use a specific method to calculate total enthalpy difference, or are we just going to use whichever method we are more comfortable with?

We can use any method, but generally the question can be solved by one method only (as it might be at a constant pressure or volume)
