Answer:
The value of pressure must be increased double times.
Explanation:
pV = nRT ( the Ideal Gas Law ) =>
p = nRT / V
So, when T is doubled, we write 2T to the formula:
p(new pressure) = nR x 2T / V = 2 x p(original)
=> If the temperature of a gas doubles and the volume stays the same, the value of pressure must be increased double times.
I hope this answer can help you. Have a nice day!
