The segments of the graph are;
1) The substance is heated 2) Three states of matter 3) There are 3 changes of state 4) b 5) b and d 6) a, c and e 7) c 8) e 9) a 10) d 11) solid 12) b
What is a heating curve?
A heating curve is a graph that illustrates how a substance's temperature changes in response to addition or removal of heat. Typically, the curve is made up of various segments that represent various phases and physical states. The temperature is shown on the y-axis, and the amount of heat added or removed is represented on the x-axis.
Understanding the energy shifts linked to phase transitions and the behavior of substances as they change states can be done with the help of heating curves.
