why molecules vibrate even at absolute zero of temperature?
Homework Answers
Ans :
The small molecules behave according to law of quantum mechanics. The molecules vibrate at different energy levels according to the temperatures they are exposed to. The higher the temperature , more is the energy level and hence higher the vibrations. At lower temperatures such as absolute zero , the vibrations of the molecules decrease but does not approach zero in any case. This is called as zero point energy.

The third law of thermodynamics relates the entropy (randomness) of matter to its absolute temperature. Which of the following statements are in agreement with the third law of thermodynamics? Check all that apply. Check all that apply. At absolute zero, the interatomic distance within a crystal is minimized. As the temperature of a perfect crystal increases, the random vibrations of the molecules decrease. At zero degrees kelvin, substances maximize entropy. In a gaseous state, the entropy of the system is...
