1. The problem statement, all variables and given/known data Air in an automobile tire is initially at -10oC and 190kPa. After the automobile is driven while the temperature rises to +10oC. 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 P1/T1=P2/T2 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?
