    Problem If gamma=1.67 and R=8.314 J/mol K, find Cv and Cp. Key Concepts Cv=R/(gamma-1); Cp=gamma R/(gamma-1) Solution Cv=8.314/(1.67-1)=8.314/0.67=12.41 J/mol K. Cp=1.67×12.41=20.72 J/mol K. Answer Cv=12.41, Cp=20.72 J/mol K (monatomic) Concept Check gamma=5/3~1.67 is monatomic gas. Common Mistakes Inverting the formula. Practice Tip Cv=R/(gamma-1).

    Problem 5 moles of a gas heated at const P; T rises 200 K; Q=29100 J. Find Cp per mole. Key Concepts Q=nCp dT; Cp=Q/(n dT) Solution Cp=29100/(5×200)=29100/1000=29.1 J/mol K. Answer Cp = 29.1 J/mol K (diatomic gas) Concept Check Cp=29.1 confirms diatomic gas (7/2 R). Common Mistakes Using n=1 instead of n=5. Practice Tip…
