Demonstrate the Second Law of Thermodynamics with this Thermoelectric Demonstrator. Immerse one of the aluminum legs into ice cold water and the other leg into hot water to demonstrate how heat transfer can be converted to electrical energy. This conversion will turn the turbine. Demonstrate the reverse effect of converting electrical energy to heat energy by plugging the apparatus into a DC power supply. In this application, DC current is given to the unit so one of the strips will heat up and the other will remain cold.

The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time. The total entropy can remain constant in ideal cases, but in all spontaneous processes, the total entropy always increases and the process is irreversible.

Includes a set of two 24” banana connecting cords and a detailed activity guide.
