Question

Which of the following statement given below are correct for monoatomic gas?

I. C_v = `3/2 "R"`

II. C_p = `5/2 "R"`

III. Cp − C_v = 2R

IV. `"C"_"p"/"C"_"v" = 5/3`

विकल्प

• I only

• I, II and IV

• III only

• None

Answer 1

I, II and IV

Explanation:

C_p = `5/2 "R"`

C_v = `3/2 "R"`

∴ `"C"_"p"/"C"_"v" = 5/3`
