327° C
The initial temperature of the gas is 27°C
We need to find the final temperature.
If we assume the initial pressure is y
The final temperature will be 2y
Using the pressure law;
[tex]\frac{P1}{T1}=\frac{P2}{T2}[/tex]
Therefore,
[tex]T2=\frac{T1P2}{P1}[/tex]
[tex]=\frac{(300)(2y)}{y}[/tex]
[tex]= 600 K[/tex]
Therefore, the new temperature is 600 K or 327° C
