Which of the following pieces of data can we obtain from a heating curve?

Question

Quizplus · Accepted Answer

A heating curve shows the temperature vs. time graph of a substance as it is heated, and includes heating and cooling phases, and phase changes. Therefore, we can obtain all of the choices from a heating curve. The boiling point of a liquid can be found from the flat section of the heating curve when the temperature doesn't change during a phase change. The melting point of a solid can be found from the flat section of the cooling curve when the temperature doesn't change during a phase change. The specific heat of a solid can be calculated from the sloping sections of the heating or cooling curve using the equation Q = m*c*ΔT.
