Problem Statement

This assignment is meant to be completed with Homework $2$ and will be completed in groups $4$ students. Your goal is to construct a Concept Map that illustrates how key concepts relate to the $1^{st}$ Law of Thermodynamics. For full credit, one should be able to use your Concept Map to develop a useful form of the $1^{st}$ Law of Thermodynamics based on the information given in a problem statement, combined with your engineering assumptions. Doing this is often one of the first steps in solving the problem $($after drawing a sketch and listing givens, finds, and assumptions of course$).$

Your maps should:

describe the concepts verbally $($you may include pictures$),$

include equations wherever appropriate, and

incorporate the concepts listed below at a minimum. $($You may include additional concepts, but you must show their relation to the $1^{st}$ Law of Thermodynamics.$)$
