Answer
No, the pressure increases by a factor of 1.08
Work Step by Step
Heating the gas from 25 C to 50C:
The ideal gas law deals with Kelvin Temperature so we must convert these to K by adding 273. This would be 298 K and 323 K. The change in temperature is therefore only a factor of (323/298 = 1.08).
Therefore, we have
PV = nR(1.08T)
To balance both sides, we multiply the left side by 1.08.
Therefore, the pressure increases by a factor of 1.08, not 2
