Can you find the second law of Thermodynamics in these pictures?

*The Chocolate Chip Motor
Entropy = Measure of Disorder
The Second Law of Thermodynamics:
An Ordered System will Naturally Tend to Disorder
It Requires Energy to Create Order out of Disorder
Order = Stored Energy
The Second Law of Thermodynamics also works in Reverse
The Natural Tendency of an Ordered System to become Disordered can be exploited
to do Work,
to produce Mechanical Energy.
As Order goes to Disorder, we can extract Energy.
The Entropy Engine
Order --> Entropy* + Energy
*Entropy = Disorder
The Chocolate Chip Engine Apparatus:
Soda pop (preferably clear)
Chocolate Chips
Clean Beaker
Soda Pop is in an Ordered state
(Lots of CO2 in small volume)
Soda Pop will spontaneously go to a Disordered state (Soda Pop will
go flat) (CO2 in large volume)
A specially engineered catalyst can speed up the transition to disorder
AND permit us to do mechanical work.
This special catalyst is a chocolate chip.
This is the Second Law of Thermodynamics at Work.
I think it is beautiful.
