So what gives? Why can't you get your energy back by simply reversing the process? This will always happen no matter how perfect your system is because there will always be friction involved and heat transferred whenever anything, well, happens. Furthermore, the second transaction took away another 7 cents from someone else's pocket. If you open a store and sell that candy bar for $1.00, you'll still only have $1.93. Entropy is the tax on the transaction that is energy transfer. The transaction itself cost you 7 cents, but provides no value to you. You now have 93 cents and $1.00 worth of chocolate, or $1.93 of value. Say you go to the store with $2.00 and you buy a $1.00 candy bar. That's what entropy really is - the loss of available energy in a system (or the destruction of exergy for precocious 5-year-olds).Ī better 5-year-old example: Think of entropy like a tax. You got less energy back than you put in initially. Your battery only charged back up to 80%. Here's where entropy comes in: you pour the liter through the water wheels and you're disappointed because some of the energy is missing.

You buy really expensive equipment to make sure you get all of your energy. In order to do this you set up a system of water wheels hooked up to generators so that you can get your energy in the form of electricity again and put it back into your battery.

The battery gets down to 30% doing this and then you decide you want to get that energy back. You run your motor using a battery that starts out at 100% charge. Say you have a liter of water and you lift it 5 meters above the ground using an electric motor. I'll try to make this as understandable as possible, but I can't guarantee that a 5-year-old will get it. Entropy is a well-understood thermodynamics concept.

People love to tell you that entropy is randomness or disorder or chaos - educational TV programs fall into that trap all the time. The concept of entropy is also a part of human physiology and behavior, it can affect your health, relationships, finances, and many other aspects of your life in a positive or negative way, depending on your response to its different levels.Essentially every answer in here is incomplete or oversimplified.Recent research reveals that a clock which emits the maximum entropy shows the most accurate time.Human-made things such as machines, furniture, and devices are less entropic than natural objects, because they are built to stay or function in an optimum, concentrated, and organized manner.A cosy campfire, boiling water, melting ice, cooking popcorn, and brewing tea - all these activities are a result of entropy, and even the universe is said to be tending towards higher entropy.This is mainly because randomness or chaos is considered an unavoidable part of almost every process. Entropy is not just limited to physics and chemistry, there are various applications of this concept in sociology, psychology, business, philosophy, biology, climate change, information systems, and many other disciplines.

Interesting Facts About Entropy Source: Alexander Andrews/Unsplash In the context of macroscopic systems, both entropy and enthalpy are considered as fundamental quantities, but when quantum mechanics is taken into account, then these quantities become derivable.
