A car starts out when the air temperature is 288 K and the absolute (total)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 their volume does not change?
A)129 kPa
B)483 kPa
C)507 kPa
D)517 kPa
E)532 kPa

Using the ideal gas law, the pressure is proportional to the temperature when volume is constant. The new pressure is calculated as (298 K / 288 K) * 500 kPa = 517 kPa.
