Exercise 18.26

Nitrogen gas ( = 1.4) at 31 C is compressed adiabatically until its volume is reduced to one-fourth of its initial value.

Part A

By how much does its temperature increase?T =

PS: Two other people got it wrong. this is the 3rd time i post this question the answer is neither 24 or 27. I would appreciate a correct answer

TV^(y-1)=constant

where y = 1.4

T2/T1=(v1/v2)^(y-1)=4^0.4=1.741

change in temperature = T2-T1=1.741T1-T1=0.741T1=0.741*31=22.971 degree celsius
