Energy added diagram kjthe values along the x-axis

Associated with each DL meeting there is an Exit Handout. It will contain the homework assignment you must complete before coming to the next DL meeting. Other online activities are for your benefit. They do not introduce new material, but contain additional practice exercises and presentations that you might find useul.

Assignments labeled FNT (For Next Time) are questions to answer, or modeling exercises to perform, etc. You must bring your response to all FNTs to the next DL meeting. Sometimes your DL instructor will ask you to hand them in. Sometimes your instructor will simply check off that you made a serious effort in responding to the FNTs. The time and thought you put into the FNTs will affect your performance on course exams.

The values along the x-axis (146 kJ, 480 kJ, etc are the amounts of energy that must be added to get the 1.0 kg of water from an initial temperature of 200 K to the next phase change. For example, 480 kJ is the total amount of energy that must be added to the water starting at the initial temperature of 200 K to completely melt all the ice.

iv. C to B. v. A to C
Do not make any calculations to answer these questions. Simply estimate values from the graph.

1.1.3-1) Neatly write out all of the energy-system diagrams, with the accompanying three-phase diagrams, requested in DL Activity 1.1.3. Remember that complete energy-system diagrams always include algebraic expressions of energy conservation. Refer to the Energy-Interaction Model discussion in the online resources.
