What is the tire pressure in Pascals and the new tire pressure?

0 votes

An automobile tire is inflated with air originally at 10.0°C and normal atmospheric pressure. During the process, the air is compressed to 32.0% of its original volume and the temperature is increased to 43.0°C.

(a) What is the tire pressure in pascals?

(b) After the car is driven at high speed, the tire's air temperature rises to 85.0°C and the tire's interior volume increases by 3.00%. What is the new tire pressure (absolute) in pascals?
