At ordinary temperatures, the molecules of an ideal gas have only translational and rotational kinctic energies. At higher temperatures, they may also have vibrational energy. As a result, at higher temperatures

Options

  1. AC_v=3 R / 2 for monatomic gas
  2. BC _ r 3 R / 2 for monoatomic gas
  3. CC_v 5 R / 2 for diatomic gas
  4. DC _ r 5 R / 2 for diatomic gas

Correct answer

D. C _ r 5 R / 2 for diatomic gas

Step-by-step solution

C_ v = f 2 R , where f is the degree of freedom
