The concept of entropy which was introduced by Clausius in 1850 as a thermodynamic property has been extended to the economics theory, information theory, and others. Even though "entropy" is used in many fields of science, it is not easy to understand the concept of entropy, as well as describing it by words/terms. In this paper, we investigated an appropriate way of representing the concept of entropy by words. At first, we surveyed the commonly used words in describing the concept of entropy. We pointed out the problem that the language expression does not accurately represent the entire concept of entropy. Secondly we examined the correlation between the thermodynamic entropy calculated from the particle animations simulating the molecular motion and the psychological quantity obtained by showing those animations to participants. As a result, we found that the representation of the word "degree of diffusion" has relatively good correlation with the entropy value.
