Heating Curve

[TanveerDhaliwal3G]

How do you read and interpret a heating curve?

The areas on the graph where the lines seem to go flat are areas in which the heat being added to the substance only serves to contribute to the substance's phase change as opposed to increasing the temperature of the substance, whereas areas where the function increases are indicative of temperature increasing relative to the heat added

Adding onto what the person before me said, the steeper the heating curve, the lower the heat capacity, and vice versa - the shallower the heating curve, the higher the heat capacity.

The flat lines on a heating curve represent the deltaH(fusion) or the deltaH(vaporization) depending on where the horizontal line is. The increasing diagonal lines are representing the q=mcAT as we are heating the substance with a certain heat capacity.

The slopes of the curves are the period of times where it is in its specific phase but the flat area of the graph is when the substance is changing from one phase to the next.

The plateaus are places of phase change while the positive slope areas is where temperature is increasingly the system.

[Jesse Anderson-Ramirez 3I]

flat areas of the graph are where phase changes are occurring. At these instances temperature is constant because all energy is being used to change phases.
