Explain using the relevant concepts of the Particle Model of Thermal Energy, not by doing any calculations.? 4.1-1) These questions deal with some new concepts and vocabulary that we will use in Chapter 4. Refer to Chapter 4, as well as to everything you have learned in this course up to now, to help you answer the following prompts. (a) What energy systems contribute to the internal energy, U? At temperatures below a 1000 K, which energy systems change, and thus contribute to ∆U? (b) In the equation “∆U = Q + W” why does the U have a “∆” in front of it, but Q and W do not have “∆”s? (You are expected to answer this based on what you learned in Chapters 1 and 2. You should know it.) (c) In your own words, what is a state function? Which of the following are state functions and which are processes? How can you tell? Eth Ebond Q U P T W KE PE (d) How are states and processes represented on state diagrams? (e) When the volume of a gas is changed, the work done is: V2 W = − ∫ P(V )dV How can this work be found graphically on a PV state diagram? V1...
