An automobile tire is inflated with air originally at 10°C and normal atmospheric pressure. During the process, the air is compressed to 26 percent of its original volume and the temperature is increased to 37°C.
(a) Determine what is the tire pressure?
___________Pa
(b) After the car is driven at high speed, the tire's air temperature rises to 85°C and the tire's interior volume increases by 3 percent. Evaluate what is the new tire pressure?
