Question

please answer it all and correct

An automobile tire is filled to a gauge pressure of 151 kPa when its temperature is 20 C. (Gauge pressure is the difference between the actual pressure and atmospheric pressure.) After the car has been driven at high speeds, the tire temperature increases to 53 C 1) (a) Assuming that the volume of the tire does not change, and that air behaves as an ideal gas, find the gauge pressure of the air in the tire kPa Submit You currently have 2 submissions for this question.

Explanation / Answer

answer1

Given::

initial T =20 C = 293 K

Final T =53 C = 326 K

gauge pressure =151kPa,

actual pressure now can be calculated as

P = 151kPa + 101.325kPa = 252.325kPa

since volume doesnot change therefore using Gay-Lussac's Law;

P1/T1 = P2/T2

252.325/293 = P2/326

P2 = 280.744 kPa
