Key Concepts

Latent Heat

Latent heat is the amount of heat required to effect a phase change in a substance at a constant temperature. This concept explains the flat segments in a heating curve, where energy input is absorbed in overcoming the intermolecular forces during melting or boiling.

Specific Heat Capacity

Specific heat capacity is the quantity of heat needed to raise the temperature of a given amount of a substance by one degree. It determines the slope of the temperature increase during heating in regions where the substance remains in the same phase.

Heating Curve

A heating curve is a graphical representation that shows how a substance's temperature changes as heat is added. The curve typically features segments where the temperature increases steadily within a phase and flat regions where the temperature remains constant during a phase transition.

Phase Transitions

Phase transitions occur when a substance changes from one state of matter to another, such as solid to liquid or liquid to gas. On a heating curve, these transitions are represented by horizontal lines, where the added heat is used to change the phase rather than to increase temperature.
