Given
The volume reduced by 20% after compression

Final temperature =157°C

Changing temperature in Kelvin =157+273=430k
Let initial volume =100

Then final volume =80

So as we know, PV=mrt (nrt)

M, r and p=constant

V1/t1=V2/t2

100/t1=80/430

T1=100x430/80

T1=100x430/80

T1=100x5.375

T1=537.5k

Changing it in Celsius

T1=537.5-273=264.5°C

This is ur ans hope it will help you in case of any doubt comment below
