Yes, 174 K is right answer.
&gama; = 1.6554.
T1/T2 = (V1/V2)^1.6554-1.
T2 = T1/2.87 = 500/2.87 = 174K.
&gama; = 1.6554.
T1/T2 = (V1/V2)^1.6554-1.
T2 = T1/2.87 = 500/2.87 = 174K.

I think the correct answer is 174.
Use PV k power gamma = c.
Cp-cv=R find gamma cp by cv.
Use PV k power gamma = c.
Cp-cv=R find gamma cp by cv.
