A car starts out when the air temperature is 288 K. The air pressure in the tires is 500 kPa. After driving a while, the temperature of the air in the tires increases to 298 K. What is the pressure in the tires at that point, assuming the volume remains constant?

Question

Quizplus · Accepted Answer

Using the ideal gas law, if volume is constant, pressure is directly proportional to temperature. P1/T1 = P2/T2, so P2 = P1 * (T2/T1) = 500 kPa * (298 K / 288 K) = 517 kPa.
