(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Air in an automobile tire is initially at -10^{o}C and 190kPa. After the automobile is driven while the temperature rises to +10^{o}C. Estimate the new pressure in the tire. State all assumptions that you make in providing this estimate.

2. Relevant equations

Pv=nRt

3. The attempt at a solution

As the temperature increases the air pressure will increase in the tire

I assume that the v n and r in the equation are constant in this problem

therefore the P_{1}/T_{1}=P_{2}/T_{2}

which is 190*283/263 = 204kPa

I could be completely wrong here as there is no answer given to this question, can someone share some thoughts?
