How does the second law of thermodynamics explain a spontaneous change in a system that becomes more ordered when that process is exothermic?
Consider the system shown in Figure 16.9. What is the change in entropy for the process where the energy is initially associated only with particle A, but in the final state the energy is distributed between two different particles?
What happens to the entropy of the universe during a spontaneous process?
Many plastic materials are organic polymers that contain carbon and hydrogen. The oxidation of these plastics in air to farm carbon dioxide and water is a spontaneous process; however, plastic materials tend to persist in the environment. Explain.
