Question1)Will a change in temperature affect the pressure that is measured using a gauge? If so, use kinetic molecular theory to explain how pressure and temperature are related.

2. Describe quantitatively how pressure and temperature are related. This explanation should include an equation.

3. If a football is initially inflated to 12.5 psi as measured with a gauge at a temperature of 22 °C, what will the gauge pressure of the football be when the temperature is 9 °C?

4. When moved from a cold environment to a warm environment about how long will it take the temperature of the footballs to reach the temperature at which the pressure was originally measured? Use Figures 21 and 22 on pages 42 and 44, respectively, of Appendix 1 of the NFL report by Wells et al.

5. Are the two gauges calibrated such that they read the same pressure? Explain using the data in Tables 1 and 2.

6. Do the two gauges show a consistent difference? Explain using the data in Tables 1 and 2.

7. Use the data from Tables 1 and 2, your answers to the previous questions, and the Ideal Gas Law to determine if the Patriots deflated the footballs. Make sure to consider all possible scenarios, detail how you analyzed the data, and explain how you came to your conclusions.
