A 400-L Container Is Divided into Two Equal Parts by a a Rubber

question 95

Multiple Choice

A 40.0-L container is divided into two equal parts by a rubber membrane. One half of the container has 1.80 moles of an ideal monatomic gas at 270 K, and the other half is a vacuum. The container does not allow any gas to escape but is free to exchange heat with the surroundings. The membrane breaks, the gas expands isothermally and eventually the gas reaches a new equilibrium condition occupying the entire volume. What is the change in entropy of the gas?

• A) 10.4 J/K
• B) 9.16 J/K
• C) 12.5 J/K
• D) 14.3 J/K
• E) 16.4 J/K
