Problem: 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.

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.
