The answer is 596.3K.

This is a simple example of Charles' law

V1T1=V2T2,

which states that the volume of a gas is directly proportional to its temperature in K.

We know V1 = 4.5L, T1=(25+273.15)=298.15K, and V2 = 9L, therefore

T2=V2V1T1=94.5298.15=596.4K -> double the volume translates to double the temperature, and vice versa.
