Construct a concept map encompassing the ideas behind the first law of thermodynamics.

Solutions

Expert Solution

To construct a concept map, one must first start with the most general concepts. These concepts are not defined by or in terms of other concepts discussed in those sections. In this case, we are constructing a map for the first law of thermodynamics. After giving the definition, the concept can be broken up into two subtopics: functions of state, path-dependent functions. Functions of state should contain a discussion of ΔU. Path-dependent functions should have a discussion of work (w) and heat (q). In the path-dependent functions subsection, there should be a discussion on the nomenclature for determining heat and work flow in and out of the system. Then, there should be a subheading for work, discussing the various forms of work (such as P–V work, for instance). A discussion of heat should contain subheadings for enthalpy at constant volume and pressure.

The project is to "Design and build an experiment to verify the first law of thermodynamics by stirring air with an electric motor powered paddle, in a well-insulated container." We are planning on finding the work of the motor and seeing if it equal to the change in internal energy of the container. The only problem is that we are confused on how to find the internal energy. What would be the best/easiest way to solve this? Also since the...
