HELP!! A bicycle tire is filled with air to a pressure of 76 psi, at a temperature of 18°C.?
A bicycle tire is filled with air to a pressure of 76 psi, at a temperature of 18°C. Riding the bike on asphalt on a hot day increases the temperature of the tire to 58°C. The volume of the tire increases by 3.5%. What is the new pressure in the bicycle tire?
Use combined gas equation:
P1V1/T1 = P2V2/T2
76 * 1.00/291 = P2*1.035/331
76*1.0*331 = P2*1.035*291
P2 = 25,156/301.185
P2 = 83.5
Answer: 83.5psi
