A gas contained in a steel tank has a pressure of 1.5 atm at a temperature of 320 K. What will be the gas pressure when the temperature changes to 450 K, at constant amount of gas and volume?

We use the combined gas law to solve this problem, as the amount of gas and volume are constant.

P1/T1 = P2/T2

Plug in the given values:

(1.5 atm)/(320 K) = P2/(450 K)

Solve for P2:

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. The answer is choice E.
