5.99 cubic meter of gas initially at 1 atm. pressure and 273K is placed under pressure of 4 atm. pressure.. The final temp is measured at 25 deg C. What is the final volume.

Do I convert the 273K to celcius, which worked out to 0 deg cel?? is that correct?

Do I use the liquid volume expansion in this equation??

I am not to sure, thanks.
