Because we are looking for the volume change caused by a temperature change at constant pressure, this is Charles’s law.
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]We have to convert temperature from degrees celsius to kelvin.
25 degrees celsius = 25 + 273 = 298 K
2 degrees celsius = 2 + 273 = 275 K
V2 = (V1/T1) x T2
V2 = (450 L/298 K) x 275
V2 = 415.3 L
