The molar specific heat at constant pressure of an ideal gas is 7 2 R . The gas is made up of molecules which are ( R is the universal gas constant)

Options

  1. APolyatomic
  2. Btriatomic
  3. Cmonoatomic
  4. Ddiatomic

Correct answer

D. diatomic

Step-by-step solution

Given: C_P= 7 2 R , and C_P-C_V=R C_V=C_P-R= 7 2 R-R= 5 2 R = C_P C_V = 7 2 5 2 = 7 5 which matches the _ diatomic = 7 5 The gas consists of diatomic molecules!
