1. The problem statement, all variables and given/known data i am just reviewing for a test and doing some practice questions. i disagreed with one of the answers and now i am uncertain about the relationships between pressure volume and temp. i thought the relationships were: as pressure increases, temp increases, volume decreases (any combo of these three) as pressure decreases, temp decreases, volume increases (any combo of these three) and just incase these are correct and maybe im interpreting the question wrong, the questions is basically given a picture of piping varying in size, at which point in the pipe is the water under the least pressure. i thought i would be at the point of largest volume, but the answer according to my teacher is a point with the least volume.
