Verbal Expression of the Entropy Concept

In this paper, we investigated the way of representing the concept of entropy in word. At first, we pointed out the problem that the verbal 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 higher correlation with the entropy value.
