here's another one that stumped me
An automobile tire is inflated with air originally at 10C and normal atmospheric pressure. During the process the air is compressed to 28% of its original volume and the temperature is increased to 40C.
a) what is the tire pressure?
b) after the car is driven at high speed the tire air temperature rises to 85C and the interior volume of the tire increases by 2%. what is the new tire pressure (absolute) in pascals?
the only reason why i don't know how to start this problem is because i don't know what is the initial pressure. all it says is "normal atmospheric pressure"
