In this episode, the Standard Deviants tackle thermodynamics. The study of thermodynamics involves the conversion of energy to useful forms of power. They discuss the three laws of thermodynamics, heat engines, work processes, heat sources, and entropy. Part of the "Standard Deviants School: Physics" series.

The study of thermodynamics can lead to predicting how chemical reactions will proceed or how much energy is required or released during the reactions. To better understand chemical reactions, a new thermodynamic value called “enthalpy” is introduced. Students will examine the practical applications of bond enthalpies, calorimetry, and other measurements of the energy in chemical reactions. They will also see how the understanding of thermodynamics and enthalpy is helping scientists optimize the use of crop waste for biofuels and build more efficient automobile engines. Part of Chemistry: Challenges and Solutions Series.
Some chemical reactions happen spontaneously, like metal rusting. Other reactions are non-spontaneous and need to absorb energy in order to occur. Using the Second Law of Thermodynamics, the principle of entropy, and the calculation of Gibbs free energy, scientists can predict which reactions will occur and vary the conditions to make more of the desired products. In equilibrium reactions, both products and reactants are always present. Equilibrium reactions in the human body are essential for life and can be exploited in chemical manufacturing as well. Part of the series Chemistry: Challenges And Solutions.
Thermodynamics deals broadly with the conservation and conversion of various forms of energy. It also describes the relationships between energy and the changes in properties of matter. Other topics covered include Hess's law, the laws of thermodynamics, and the Gibbs free energy. Part of the "Chemistry" series.
