Mario Cantrell · Answer 1

For an ideal gas, we use the ideal gas equation to relate pressure, volume and temperature changes. It is expressed as:

PV=nRT

For this case, we set V, n as constant.

P/T = nR/V = constant = k

P = kT

P1/T1 = P2/T2

P1/T1 = 2P1 / T2

T2 = 2P1 (T1) / P1

T2 = 2T1

Therefore, in order to double the pressure of the system, we need to double the temperature as well at constant volume and number of moles.
