How does temperature affects tire pressure?
I think nothing will happen and there is no connection between temperature and tire pressure.
The Independent Variable
The condition that will change is the temperature.
The Dependent Variable
The condition that will be affected by the change is the tire pressure.
I will measure the tire pressures at different temperatures and check for any changes.
On different days and different times, I will measure the temperature using a thermometer. I will then measure the tire pressure of the two front wheels using a tire pressure gauge. I will take the average pressure of the wheels and use this on my graph. To eliminate the effect on tire pressure caused by car usage, I will only measure after the car has been parked for at least four hours.
When the temperature went from 5 to 50 Fahrenheit, the average tire pressure went from 34.4 to 38.4 psi (pounds per square inch). The graph line is nearly a straight line. On average, the tire pressure increases by 0.0808 psi for every increase of 1 degree Fahrenheit in temperature. It takes an increase of 11.25 degrees Fahrenheit for the tire pressure to increase by 1 psi.
The temperature has a strong effect on tire pressure as my graph shows. The tire pressure rises and falls with the temperature. Compared to my results, my hypothesis is incorrect.
