Answer: T = 384 K

Explanation: For this problem we will use Charles Law for gases. The formula is expressed as the ratio of volume per unit temperature having a constant pressure.

V1 / T1 = V2 / T2 derive to find the new Temperature T2

T2 = V2 T1 / V1

= 150 L (256 K) / 100 L

= 384 K

Cancel out the units of Liters so the remaining unit is in Kelvin.
