Agreed 596K since Charles' Law requires degreesCelsius to be converted to Kelvin

I have to disagree with the answer to the question because in order to find temperature the units must be in kelvin you can not use Celsius in the equation. the answer to this would be 596k or 323 Celsius

25+273=298k

V1=4.5L
T1=298k
V2=9L
T2?

V2*T1 9*298. = 596k - 273= 323 C
V1 4.5
