Equal volumes of two monoatomic gases, A and B, at same temperature and pressure are mixed. The ratio of specific heats (C_p/C_v) of the mixture will be

0.83

1.50

3.3

1.67

Solution

1.67

For space monoatomic space gases comma straight C subscript straight p over straight C subscript straight v space equals space straight gamma space equals space fraction numerator begin display style 5 over 2 end style straight R over denominator begin display style 3 over 2 end style straight R end fraction space equals space 1.67 therefore space Equal space volumes space of space two space monoatomic space gases space are space mixed. therefore space straight gamma space will space remain space the space same
