The ratio of the molar specific heat capacities of monatomic and diatomic gases at constant pressure is

Options

  1. A1: 7
  2. B5: 7
  3. C3: 7
  4. D2: 7

Correct answer

B. 5: 7

Step-by-step solution

For monoatomic gas, f =3 ( C _ p )₁= (1+ f 2 ) R = (1+ 3 2 ) R = 5 R 2 For diatomic gas, f =5 aligned & ( C _ p )₂= (1+ f 2 ) R = (1+ 5 2 ) R = 7 R 2 & ( C _ p )₁ ( C _ p )₂ = 5 R 2 7 R 2 =5: 7 aligned
