Problem 2.34

Find the specific heat capacities \(c_{V}\) and \(c_{p}\) for a gaseous mixture consisting of \(7.0 \mathrm{~g}\) of nitrogen and \(20 \mathrm{~g}\) of argon. The gases are assumed to be ideal.

Reveal Answer
cv=0.422 J/(g⋅K),cp=0.65 J/(g⋅K)c_{v}=0.42^{2} \mathrm{~J} /(\mathrm{g} \cdot \mathrm{K}), c_{p}=0.65 \mathrm{~J} /(\mathrm{g} \cdot \mathrm{K})
