A car tire was inflated to a pressure of 24 lb in-2 (also known as PSI) on a winter's day when the temperature was -5 °C. This pressure reading was obtained by using the standard tire pressure gauge available to purchase at many stores such as Walmart or AutoZone. Conversion of units is 1.00 atm = 14.7 lb in ². What pressure will be measured on the tire by the same pressure gauge, assuming no leaks and that the tire volume is constant, on a summer's day when the temperature is 35 °C?
