1. The problem statement, all variables and given/known data My lecture note says that "T-v diagram shows change in specific volume of a substance with respect to temperature.". Is it correct? 2. Relevant equations 3. The attempt at a solution If a(Specific Volume) "with respect" to b(Temperature), then b(Temperature) should be the independent variable. But T-v means that specific volume(v) is the independent variable right?
