Nonetheless, if a theory and its predictions have been repeatedly verified by experiment, it will be generally accepted, unless there is sufficient evidence to show it should be discarded in favor of a new theory. You would soon find that some substances actually become less soluble with increasing temperature. A hypothesis is a statement, not a question.
