The purposes of most chapter endings (except for the first and last chapters) will be similar. Chapter endings should either address and resolve or address and deepen problems that were introduced in that chapter and/or previous chapters.
Every problem won’t be resolved, but there should be some degree of closure. At the same time, the tension level will be raised by a new event or twist.
Chapters that end in this fashion will raise the interest of your readers and entice them. Answers can be provided, problems solved (completely or partially), new questions might be raised – these things might be what drives both your characters and readers into the next story event and the next chapter.
