In this paper, We examined the instruction method using verbal expressions which are easier for students to understand the entropy concept, when explaining the concept of entropy to them in the lecture of thermodynamics. The verbal expressions used in this paper were selected from our previous studies, which examined the correlation between the entropy value and psychological quantity caused by words. Using CG-animation-contents simulating the molecular motions, we examined which word is the best expression to explain the entropy concept among "randomness", "disorder", "ambiguity", "the degree of diffusion" and "the difficulty of capture". As a result, we obtained that "the difficulty of capture" is relatively useful for understanding of the entropy concept.
