Question

The statement below was made by some students describing what happened during the determination of the melting point of solids. (1) The temperature of the solid was constandt until melting started. (2) The temperature of the solid rose until melting started (3) during melting, the temperature was rising. (4) During melting, the temperature was constant.(5) the temperature continued to rise after all the solid had melted. (6). The temperature stopped rising after all the solid had melted. Which of the following gives correct statement in the right order?

Answer 1

It takes energy to melt a solid. As energy is applied to the solid, the temperature goes up until it reaches the point that the solid starts to melt. At that point, the energy being applied all goes toward melting the solid (so none of it is used to raise the temperature) and consequently the temperature stays constant until the melting process is completed. Then the energy goes back to raising the temperature (now of the liquid).
