Kate has 35 grams of xenon gas in a 15 liter tank at 11 degrees celsius and 250 atmospheres. If she heats the gas in the tank up to 2500 degrees celsius, what will its pressure be, in Kilopascals?

Use the combined gas law:
P1V1/T1=P2V2/T2
volume is constant, so
P2=P1T2/T1 temps in kelvins.
convert finally atm to Kp.
