Course contents Homework set #9 (due 6/21 at 5PM) Tire pressure Timer Notes Evaluate M Feedback Print Info The air pressure inside the tube of a car tire is 339 kPa at a temperature of 14.5 oC. What is the pressure of the air, if the temperature of the tire increases to 60.0 oC? Assume that the volume of the tube doesn't change. Submit Answer Incorrect. Tries 3/2 Previous Tries What is the air pressure inside the tube, if the volume of the tube is not constant, but it increases from 20.7 l to 21.2 l during the warming process described above?

for first part
P1/T1 = P2/T2
339 / (273+14.5) = P2/ (273 + 60)
P2 = 392.65 kPa
b) P1V1 / T1 = P2V2/T2
339*20.7 / (273 + 14.5) = P2*21.2 / (273 + 60)
P2 = 383.39 kPa
