Question

A tire is inflated to a gauge pressure of 2.0 atm. As the carvis driven the temperature of the tire increases from 20 degrees to 45 degrees and simultaneously the volume of the tire increases by 5 % . What is the gauge pressure of the tirevatvthe higher temp? A tire is inflated to a gauge pressure of 2.0 atm.

Explanation / Answer

according to unversal gas law

(PV)/T = constant

T1=20=293K

t2=45=318K

V2= 1.05V1

so ,

P1v1/T1= P2V2/T2

P2=( T2/T1 ) x    (1/1.05)x(2)

P2=2.06 atm
