A mixture contains 1 mole of helium (CP=2.5R,CV=1.5R) and 1 mole of hydrogen (CP=3.5R,CV=2.5R). If the value of CV for the mixture is xR then what is the value of x?

Solution
Given : nHe=1CVHe=1.5RnH2=1CVH2=2.5R Value of CV for mixture CV=nHeCVHe+nH2CVH2nHe+nH2 ∴CV=(1)(1.5R)+(1)(2.5R)1+1=2R Thus we get x=2
