This is a straightforward application of Charles's Law which states that at constant pressure, the volume of a gas is directly proportional to its temperature measured in kelvins. Using the formula V1/T1=V2/T2, we can solve for V2.
V1=25.5 L
T1=150+273=423 K
T2=50+273=323 K
V2=25.5 L x 323 K / 423 K
V2=19.5 L
