For this question, we can use the Combined Gas Law, which is the law and formula that perfectly correlates all 3 (volume, temperature and pressure), the formula is:

P1V1/T1 = P2V2/T2

We have:

P1 = 25 atm

V1 = 26 L

T1 = 35 K

P2 = ?

V2 = 80 L

T2 = 67 K

Now we add these values into the formula:

25 * 26/35 = P2 * 80/67

18.57 = P2*80/67

80P2 = 1244.2

P2 = 15.55 atm is the new pressure
