Now answer the following question(s): 1. Which theorem did we use to solve this problem? State the theorem.
2. What kind of lines are the parallel lines in this question, increasing, decreasing or vertical? How can you conclude?
3. In the question, in what form is the equation of the second line given? What form was it converted to? Why?
4. Find the distance between two parallel lines in this question?
5.
What is the condition for two non-vertical lines to be perpendicular according to Slopes of Perpendicular Lines theorem?
What does the converse of Slopes of Perpendicular Lines theorem state?

Which of the following statements are true? (select all that apply.) a quasi-static process is one in which the system is never far from being in equilibrium. when a system can go from state 1 to state 2 by several different processes, the amount of heat absorbed by the system will be the same for all processes. the internal energy of a given amount of an ideal gas depends only on its absolute temperature. when a system can go from state 1 to state 2 by several different processes, the work done on the system will be the same for all processes. when a system can go from state 1 to state 2 by several different processes, the change in the internal energy of the system will be the same for all processes. for any substance that expands when heated, its cp is greater than its cv.
