Chemistry heating curve

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 ...
