Please explain entropy in simple terms whitch even 14 years old can understand

Entropy is a measure of the randomness or disorder in a system. Imagine your room: if everything is neatly organized, the entropy is low. But if everything is messy and scattered around, the entropy is high. In science, especially in thermodynamics, we use entropy to describe how energy is spread out. As things mix or spread out, like heat or particles, the entropy increases. As a general rule, nature tends to move towards higher entropy, which means systems become more disordered over time.
