An automobile tire has a maximum rating of 38.0 psi (gauge pressure). Note: The gauge pressure is the difference between the total pressure and atmospheric pressure. In this case, assume that atmospheric pressure is 14.7 psi. The total pressure (gauge pressure + atmospheric pressure) in the tire after warming on a hot day is 3.96 atm.
Does the pressure in the tire exceed its maximum rating?
a) No, since 3.45 atm would result in a gauge reading of 36.0 psi.
b) No, since 3.96 atm would result in a gauge reading of 22.2 psi.
c) Yes, since 3.96 atm would result in a gauge reading of 58.2 psi.
d) Yes, since 3.96 atm would result in a gauge reading of 43.5 psi.
