The term 'chaotic tendency' is often used to describe the concept of ENTROPY, which is a measure of the amount of disorder in a system. ENTROPY is a thermodynamic property that describes the amount of energy that is unavailable for work in a system. In other words, it is a measure of the amount of randomness or disorder in a system. ENTROPY is an important concept in physics and chemistry, as it helps to explain why certain processes occur in nature. In general, ENTROPY increases over time, meaning that systems tend to become more disordered over time. This is known as the chaotic tendency.
