A gaseous mixture contains 7 g of nitrogen and 20 g of argon. Assuming them to be ideal, find the specific heat capacities \(5_{p}\) and \(5_{v}\), for this gaseous mixture. (\(Y\) for nitrogen is 1.40 and that for argon is 1.67 )
- \(5_{y}=650 \mathrm{~J} / \mathrm{kg}-K_{1} 5_{p}=420 \mathrm{~J} / \mathrm{kg}-K\)
- \(5_{y}=310 \mathrm{~J} / \mathrm{kg}-K_{1} 5_{p}=650 \mathrm{~J} / \mathrm{kg}-K\)
- \(5_{y}=420 \mathrm{~J} / \mathrm{kg}-K_{1} 5_{p}=450 \mathrm{~J} / \mathrm{kg}-K\)
- \(5_{y}=420 \mathrm{~J} / \mathrm{kg}-K_{1} 5_{p}=650 \mathrm{~J} / \mathrm{kg}-K\)
Answer
(D) 5_ y =420 ~J / kg -K_ 1 5_ p =650 ~J / kg -K
