Answer to Question #247510 in Molecular Physics | Thermodynamics for mion

Question

For a certain ideal gas Cp = 1.1 KJ/kg-K and k = 1.3 , Determine:
a. Molecular weight
b. Universal gas constant
c. Constant volume specific heat

Answer 1

c)

$k=\frac{c_p}{c_V},\implies$ $c_V=\frac{c_p}k=0.27~\frac{kJ}{kg\cdot K},$

b)

$R=c_p-c_V=8.3~\frac J{kg\cdot K},$

a)

$n=\frac{c_p-c_V}R=10.$
