Quizplus · Accepted Answer

Using the formula P1/T1 = P2/T2, where P is pressure and T is temperature:
P1 = 1.5 atm
T1 = 320 K
T2 = 450 K
P2 = (1.5 atm)(450 K)/(320 K) = 2.1 atm
Therefore, the gas pressure will be 2.1 atm when the temperature changes to 450 K, at constant moles and volume. The answer is D.
