1. ) Identify the line segment on the following diagram where the specific heat of the solid is used to calculate energy flow.
2.) Identify the point(s) on the following diagram where the removal of heat will cause some of the sample to condense .

Solution

with line segments C and G, temperature remained constant with increase in heat energy, it implies the heat energy supplied did not raise the temperature and it is used as energy flow. the input energy is equal to the output energy.

at points A,E and J the temperature is increasing with supply of heat energy, hence if supply of heat. Hence if heat is removed the sample will condense.
