Question

what is meant by entropy? plz explain with example

Answer 1

Entropy is a measure of the disorder or randomness of a system.

We see evidence that the universe tends toward highest entropy many places in our lives.

A campfire is an example of entropy. The solid wood burns and becomes ash, smoke and gases, all of which are more disordered than the solid fuel.

Ice melting, salt or sugar dissolving, making popcorn and boiling water for tea are processes with increasing entropy in your kitchen.

When you clean your room, it doesn't stay neat on its own. Unless you do work each day to keep things picked up, your shoes find their way out of the closet to the side of your bed, the jewelry, coins, and beauty products on your dresser get all jumbled up, your laundry pile grows every time you try to decide which outfit to wear and the bed covers are all scrambled.

The chaos of a teenager's bedroom is a perfect example of entropy.
