Web8 de ago. de 2024 · During the melting process, the two states—solid and liquid —are in equilibrium with one another. If the system was isolated at that point and no energy was allowed to enter or leave, the ice-water mixture at 0 o C would remain. Temperature is always constant during a change of state.

In this experiment, a solid turns into a liquid and then the liquid turns into a solid. The energy changes are examined. The students will take the temperature of stearic acid at regular intervals as they heat and cool it. They can observe the melting and freezing points of the acid and can plot a graph. WebA heating curve shows how the temperature of a substance changes as it is heated. Generally, a heating curve starts with the substance in the solid state and continues until the substance reaches the gaseous state. Notice that as heat is added to the solid, the temperature rises (A). As the solid begins to melt, the temperature becomes constant ... tpg accounts
