cp/cv = 5/3 = 1.6 this for monoatomic particle.
cp/cv = 7/5 = 1.4 this for diatomic particle.
So, cp/cv = R where, R is molar mass.
R>1.
cp/cv = 7/5 = 1.4 this for diatomic particle.
So, cp/cv = R where, R is molar mass.
R>1.

And r = 1.14 is for air not for all gases. But r>1.

It is given that the ratio of cp/cv=R which is consatant and value is 1.14 which is constant.

Ratio of cp and cv is greater then one because value of cp is greater then cv.

@Ambika: The above said is for gas. And it varies with the medium and composition.

cp/cv = 1.14.
This value is constant.
We denoted it by gama.
