C morning, the pressure in a car tire reads 28 psi on a pressure gauge. After several hours of highway traveling, the pressure ea 35 PST Assuming the volume remains constant and normal atmospheric pressure of 15 psi, what is the tire temperature? Don't forget to add the 15 psi to both 28 and 35 The tire the "gauge pressure." 55 C. 55 F 41 C 45 C 25 CExplanation / Answer
P1 = Po + dp1 = 28+15 = 43 psi
P2 = po+dp2 = 15+35 = 50 si
at constant volume
p1/T1 = P2/T2
T2 = P2*T1/P1
T2 = (50*(273-3))/43 = 314 K
t2 = T2 - 273 = 41 <--------answer
