Given below are observations on molar specific heats at room temperature of some common gases. The measured molar specific heats of these gases are markedly different from those for monatomic gases. Typically, molar specific heat of a monatomic gas is 2.92 cal/mol K. What can you infer from the somewhat larger (than the rest) value for chlorine ?

Options

  1. Aat room temperature, chlorine also has vibrational modes of motion besides rotational and translational modes
  2. Bat room temperature, chlorine has only vibrational modes of motion.
  3. Cat room temperature, chlorine has only rotational modes of motion.
  4. Dat room temperature, chlorine has only translational modes of motion.

Correct answer

A. at room temperature, chlorine also has vibrational modes of motion besides rotational and translational modes

Step-by-step solution

Correct Option is : (A) at room temperature, chlorine also has vibrational modes of motion besides rotational and translational modes of motion.
