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?

Question

To solve this problem, we can use the combined gas law:

(P1/T1) = (P2/T2)

where P1 and T1 are the initial pressure and temperature, and P2 and T2 are the final pressure and temperature.

Substituting the given values:

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

Solving for P2:

P2 = (1.5 atm / 320 K) * 450 K
P2 = 2.1 atm

Therefore, the gas pressure will be 2.1 atm when the temperature changes to 450 K. Hence, the best choice is D.
