Two moles of an ideal gas (Cv,m=12.5 JK−1mol−1) are at 300 K and 5 – InterviewSolution

1.	Two moles of an ideal gas (Cv,m=12.5 JK−1mol−1) are at 300 K and 5 dm3. If the gas is heated to 600 K and the volume changed to 10 dm3, calculate the entropy change. (take ln2=0.7, R=8.3 Jmol−1K−1)
Answer» Two moles of an ideal gas $(C_{v, m} = 12.5 J K^{- 1} m o l^{- 1})$ are at $300 K$ and $5 d m^{3}$ . If the gas is heated to $600 K$ and the volume changed to $10 d m^{3}$ , calculate the entropy change. (take ln2=0.7, $R = 8.3 J m o l^{- 1} K^{- 1}$ )
