The contents of the closed box in each of the following illustrations represent a system, and the arrows show the changes to the system during some process. The lengths of the arrows represent the relative magnitudes of q and w. (a) Which of these processes is endothermic?
Imagine that you are climbing a mountain. (a) Is the distance you travel to the top a state function?
The diagram shows four states of a system, each with different internal energy, E. (a) Which of the states of the system has the greatest internal energy?
The diagram shows four states of a system, each with different internal energy, E. (c) Write an expression for the difference in energy between State C and State D.
Imagine a container placed in a tub of water, as depicted in the accompanying diagram. (a) If the contents of the container are the system and heat is able to flow through the container walls, what qualitative changes will occur in the temperatures of the system and in its surroundings? From the system's perspective, is the process exothermic or endothermic?
