I know that this is not a project related question and I promise not to make it a habit, but my physics teacher stumped our class with a question today and I thought of all the smart people on Instructables one of you would know the answer. I have already search google to no avial. Is it possible to determine the volume of a flask given only the starting temperature/pressure and the final temperature/pressure? The number of moles are unknown. If it is possible how do you determine it? Thanks for your help!
