Conceptual Questions 1. State an example of a process that occurs in nature that is as close to reversible as it can be. Solution Some possible solutions are frictionless movement; restrained compression or expansion; energy transfer as heat due to infinitesimal temperature nonuniformity; electric current flow through a zero resistance; restrained chemical reaction; and mixing of two samples of the same substance at the same state. 2. Explain in practical terms why efficiency is defined a...
