170C=170+273=443K
now, as the gas is compressed suddenly, it means that the compression is done such that there is no exchange of heat with the surroundings...
therefore, the gas undergoes an adiabatic process.
for monoatomic gas adiabatic exponent gamma=5/3=g
using the equation for adiabatic process TVg-1=constant
if T1,V1 be initial temp. and volume and T2,V2 be final temp.. and volume.
u haveT1V1g-1=T2V2g-1
V2=V1/8
therefore
T2=T18g-1=T1(8 )2/3=4T1=4(443)= 1772K
=1499 C????
