Homework Statement
automobile tire is inflated with air originally at 10 degrees celcius and at normal atmosphere pressure. During the process the air is compressed to 28% of its original volume and the tempreture is increased to 40 degrees celcius, what's tire pressure?
Homework Equations
pv=nrt so p=nrt/v
The Attempt at a Solution
p=(not sure what to use for n)(.0821)(30K)/(72)
i subracted 28 from 100 to get 72 for volume not sure if that's right(i also posted this question in the advanced physics forum by too i wasnt sure where to put it)
