The internal energy U , pressure P and volume V of an ideal gas are related as U = 3 P V + 4 . The gas is

Options

  1. Aeither monoatomic or diatomic
  2. Bpolyatomic only
  3. Cmonoatomic only
  4. Ddiatomic only

Correct answer

B. polyatomic only

Step-by-step solution

U = 3 P V + 4 n f 2 R T = 3 P V + 4 f 2 P V = 3 P V + 4 f = 6 + 8 P V Since degree of freedom is more than 6 therefore gas is polyatomic
