In this question, since we are dealing with all 3 characteristics given to gases, we can use the Combined gas Law, which will show the relationship among all 3, temperature, volume and pressure, the formula for this law is:
P1V1/T1 = P2V2/T2
We have:
P1 = 1 atm
V1 = 25 L
T1 = 100 K
P2 = 6 atm
V2 = ?
T2 = 300 K
Now we add these values into the formula:
1 * 25/100 = 6 * V2/300
0.25 = 6V2/300
75 = 6V2
V2 = 12.5 Liters is the new volume
