Question

A gas has an initial volume of 2.4 L at a pressure of 1.5 atm and a temperature of 273 K. The pressure of the gas increases to 4.5 atm, and the temperature of the gas increases to 313 K.

What is the final volume of the gas?

0.70 L
0.92 L
6.3 L
8.3 L

Answer 1

Use the combined gas law: P1V1/T1 = P2V2/T2, so V2 = V1*(P1/P2)*(T2/T1).

V2 = 2.4 L * (1.5/4.5) * (313/273)
= 2.4 * (1/3) * 1.146 ≈ 0.917 L ≈ 0.92 L.

Answer: 0.92 L.
