What is the value of for mono atomic gas (ideal gas)?

Options

  1. A7 5
  2. B4 3
  3. C5 2
  4. DNone of these

Correct answer

D. None of these

Step-by-step solution

Key Idea = C _ P / C _ V where, C _ P and C _ v are heat capacities at constant pressure and volume, respectively. For monoatomic gas, C _ P =5 cal , C _ V =3 cal = C _ P C _ V = 5 3 =1.67 For diatomic gas, C _ P =7 cal , C _ V =5 cal _ V =6 cal = C_P C_V = 8 6 =1.33
