Figure 1 Figure 2 Figure 3 T-15°C T-50°C T- 50°C n moles n moles n' moles P-2 atm P-? P-2 atm All the tires of a car are inflated, each with n moles of air, to a gauge pressure of 2 atm when the temperature is 15°C (Figure 1). During the car's motion, the temperature of tires rises to 50°C due to the friction with the road (Figure 2). If we assume that the volume of the tires does not change, then this increase in temperature produces an increase in the pressure inside the tires, which leads to the explosion of the tires. In order to maintain the initial pressure (2 atm) at 50°C, the number of moles is reduced to n' moles by removing air from the tires (Figure 3). The ratio " is: n' (1 atm = 1.01 x 10$ Pa, R= 8.314 J/mol.K). 0.89 0.76 0.2 0.5 0.33
