Pressure Law - Can someone help me plan an experiment?

Homework Statement

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.

Homework Equations

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.

Hello,

Thank you for your post. Investigating the relationship between temperature and pressure is an interesting and important topic in the field of physics. I would suggest starting by setting up a controlled experiment in which you vary the temperature of the car tyre and measure the corresponding pressure using the syringe and other equipment provided.

First, make sure to record the cross-sectional area and volume of the syringe to use in your calculations. Then, you can use a water bath or a heating source to change the temperature of the tyre. As you mentioned, it is important to keep the volume of the syringe constant throughout the experiment.

To measure the pressure, you can use a pressure gauge or a manometer connected to the syringe. This will allow you to record the pressure at different temperatures. Make sure to take multiple measurements at each temperature to ensure accuracy.

Once you have collected your data, you can plot a graph of pressure vs temperature to see the relationship between the two variables. From this, you can determine if there is a direct or inverse relationship between temperature and pressure.

I hope this helps guide you in your investigation. Good luck!
