A solid material is supplied with heat at a constant rate. The temperature of the material is changing with the heat input as shown in the graph in figure. Study the graph carefully and answer the following questions:

(i) What do the horizontal regions AB and CD represent?
If CD is equal to 2AB, what do you infer?
What does the slope of DE represents?
The slope of OAgtthe slope of BC. What does this indicate?
