In an internal combustion engine, air at atmospheric pressure and a temperature of about 20 degrees C is compressed in the cylinder by a piston to (1/8) of its original volume (compression ratio 8.0).
Estimate the temperature of the compressed air, assuming the pressure reaches 38 atm.
pv = nRt
[tex]\Delta[/tex]v = [tex]\beta[/tex]Vo[tex]\Delta[/tex]T
[tex]\beta[/tex] = .0034 for air
The Attempt at a Solution
If i let p1 * v1 / T1 = p2 * v2 / T2
i can make the associations and end up with T2 = T1 * 38 / 8
however this result is incorrect.
note that i used pv = nRt for this result, i'm not sure if the other equation should be used or not,
i've only gotten garbage answers using it thus far.
Any help would be much appreciated,
