1. The problem statement, all variables and given/known data I need to investigate and model how changing temperature in a car tyre will affect the pressure. To do this, I have to use a syringe, along with any other laboratory equipment. I'm also given the cross sectional area and volume of the syringe. 2. Relevant equations 3. The attempt at a solution Can anyone please guide me on how I might do this? I've thought about it, and putting masses on the plunger and what not, but I'm guessing I want the volume of the syringe to stay constant. And I guess I'd put it in a water bath, but then I'm not sure how I'd measure pressure? It shouldn't be too complicated as it is only A-level Physics in the UK. Thank you kind sirs.
