Question

The relation between the gamma of mono atomic and polyatomic gases is

Answer 1

Answer:

which implies that γ>1 for all polyatomic gases. Now, what we seek is a way to determine the value of N for a polyatomic gas.

Answer 2

Gamma = cp / cv

As we all know that

cp - cv = R.

where,

cp is the specific heat coefficient at constant pressure,

cv is the the specific heat coefficient at constant volume,

The value of Gamma for monoatomic is

Cv=3/2R for monoatomic 

Cp=5/2 for monoatomic 

γ=5 /3 for monoatomic

γ=5 /3 for monoatomicγ= 1.66

where as,

The value of Gamma for polyatomic is

Cv=7/2R for polyatomic

Cp=9/2 for polyatomic

γ=9/7 for polyatomic

γ=9/7 for polyatomicγ= 1.33

So, For Monoatomic γ= 1.66

So, For Monoatomic γ= 1.66 For polyatomic γ= 1.33
