Homework Answers
This temperature-heat graph shows the varion of temperature versus heat. Horizontal lines show co-existence of two phases and sloped line shows single phase.
Answer for Picture 1.
at points A, B, E, F and J removal of heat will lead to decrease in temperature because going down with respect to temperature is possible.
Answer for picture 2.
Segment A-B describes the section where specific heat is used to calculate energy flow.
