Explanation:

You return home to find that your baby brother has scattered his toy trains and trucks all over the floor of your room. As you begin to pick up the toys and put them away, you realize that even though he is just a baby, he has clearly mastered: the 2nd law of thermodynamics. The second law of thermodynamics says that, when energy is converted from one form to another form, the entropy or the disorderness of a closed system increases. The process of transfer or conversion of energy is irreversible.
