Help with a physics problem? (Pressure, Temperature, Volume Problem)?

Question

At the start of a trip, a driver adjusts the absolute prssure in her tires to be 2.81 x 10^5 Pa when the outdoor temperature is 284 K. At the end of the trip she measure to the pressure to be 3.01 x 10^5 Pa . Ignoring the expansion of the tires, find the air temperature inside the tires at the end of the trip

I think temperature and pressure are supposed to increase together but I dont know how.......if you could give me some help with how to do it that would be great!!

Answer 1

Well its been some time since i touched physics but let me try...

The formula is

P1V1/T1=P2V2/T2

since V1=V2 we will be left with

P1/T1=P2/T2

2.81 x 10^5 /284=3.01 x 10^5/T2

so

T2=3.01 x 10^5 * 284/2.81 x 10^5

    =304.2 K
