Question
n1 moles of gas A are mixed with n2 moles of gas B whose ratio of specific heats are γ1 and γ2. What are the values of specific heats Cp and Cv of the mixture?
Solution
The ratio of specific heat of gas A is γ1 and that of gas B is γ2.
The specific heat of gas A and gas B at constant volume is,
respectively
The specific heat of mixture at constant volume is,
Similarly, specific heat of mixture at constant pressure is,
