Question

In case of translation-vibration transfers, there can be an increase or decrease in kinetic energy.

(a) True

(b) False

This question was posed to me by my college director while I was bunking the class.

My enquiry is from Vibrational Rate Equations topic in section Properties of High Temperature Gases of Aerodynamics

Answer 1

Correct answer is (a) True

For explanation: When a molecule undergoes a translation-vibration transfer also known as T – V transfer, molecules tend to lose or gain vibrational energy. This energy is reflected in the form of an increase or decrease in the kinetic energy of the molecule undergoing collision.
