Thermodynamics II: Entropy and Free Energy

18.0 Props for Thermodynamics II
	A toy with four layers and various sized balls and holes is used to illustrate the concept of Enthalpy.

 

18.1 Rubber Band Thermodynamics
The thermal properties of rubber will be explored in this demonstration. Will a rubber band contract or expand when heated?

 

4.1 Burning Magnesium
	A combustion reaction is demonstrated by the burning of magnesium in air, emitting a brilliant light and intense heat.

 

7.1 Endothermic Reaction
An endothermic reaction involving the combination of two solids is demonstrated.

 

7.4 Sublimation of Dry Ice
	Dry ice is placed in a plastic bag and sealed. The dry ice sublimes producing CO2 gas, which expands within the plastic bag, doing work on the surroundings.

 

7.5 MREs and Handwarmers
MREs and commercial handwarmers are displayed and activated to illustrate exothermic chemical processes and commercial uses.
